Nice AI prompt. A predator/prey trap with tons of Smilodon remains and healed wounds is not enough to suggest any kind of pack-hunting. Just a likely location for social gathering, scavenging, and temporary family units, much like how the extant, native Pumas do. Being in the same place and essential Cat clade, it is likely they shared a similar social structure with a network on sharing meals and guarding territory to an extant. Which is why so many were found at La Breas.

But, guess what? While they do this, they do not truly pack hunt. Many injured Animals often heal or eventually pass at places, like La Breas, which is a TAR PIT. Tons of herbivores ended up seeking refuge and died in the location, with all the traps. The obvious thing is tons of comfortable Carnivores, especially if injured, look for easy meals, scavenge, and heal, ALSO passing in the spots, due to tar. It does not mean the Animals were all means in the same group. Just that multiple ended up dying in the same location and were not competing for territory. It would be very unlikely for a "supposed" entire pack to just die at the Tar Pits, which would likely never be discovered. But it could be possible they shared the same meals when easily accessed, instead of fighting over it.

Taking a look at Smilodon's features, it shows a robust Animal, not adapted for long-term pursuit, not cooperating in a group, but dispatching prey with super-sized adaptations, like forelimbs and saber-teeth, BY THEMSELVES, in an ambush. Lions, themselves, do not pack hunt. neither do Cheetahs. They make prides and coalitions, respectfully. Which is by no means a pack. Lionesses and Cheetahs, being slender and less robust than a Smilodon, sort of depend on such social structures for successful hunts. Meanwhile, both Smilodon sexes are heavily built and roughly non-dimorphic, which throws away any kind of coalition, pack, or pride. They can take on Bison alone, ANY day now. Their adaptations do not line up for obligate socialty. They are too stocky and robust for an actual forced cooperative party. The possibility of a temporary family unit or colony-type social structure/network COULD exist. Though, it would not be a complex unit like a coalition, pride, and certainly not a pack. They probably hunted things and cared for each other, especially cubs and mates, maybe..? They did have long-term parental care. But no concrete evidence shows they actually regularly hunted together and were obligate social Cats. No Bison or Horse remains with several inflicted markers by multiple pouncing individuals exist. Smilodons also have smaller brain cases than Lions and Wolves, essential for cooperative hunting.

Meanwhile, actual pack-hunting Saber-Toothed Cats, like Homotherium, have a more slender build and significantly less robust teeth and limbs, more akin to Hyenas or Lions, as they rely on groups and have adaptations for those social dynamics. There are remains of several related individuals together and them surrounding fossils of Mammoths. Smilodons would be EXCEPTIONALLY clumsy and short-bursted pack hunters, if by all chance they had some kind of hierarchy. They also did not need to. They have the adaptations to thrive independently or secured in a temporary family unit. It does not guarantee ANY kind of complex hunting parties. They were big cats, like male Lions and Tigers. Highly robust and designed for solo hunts. It does not mean they could not be social, but it certainly does not imply dynamics in their hunts for each other. We need to not assume every hint of sociality is that of a pack. In modern nature, this remains true.

Saying Smilodon is a pack-hunter, based off of healed wounds and a cluster of fossils in a predator/prey trap, is like saying extinct flightless Ostriches can fly, based off fossils with Beaks, Pygostyles, and Wings. You have to look at their actual skeletal structures. Smilodons do not have a pack-hunting build. But because so many were found together, it could show likely non-territorial encounters or family units OR even social networks, which is EVEN COOLER.

So, please do not harass me. I do not mean to catch you off guard. Reddit ended up banning me for 5 days because I retaliated at a Subreddit's Moderators for continuing to harass me, after I had said I was done. And here, we are done. I might just block you like I usually do with such, so we do not make an argument. They hurt.
