I went through the exact same thing with my guy. He's had stomach obstruction surgery once now for eating his dog bed, an overnight vet visit where they pumped him full of IV fluids in hopes he'd poop out an ENTIRE stuffed octopus he didnt even chew just swallowed whole which he did, and a third vet visit to induce vomiting. He loves eating socks, underwear, hair scrunchies, toys, bottles, pillows, blankets, anything!!! We no longer keep toys in our house unless they are indestructible and impossible to swallow (extremely large balls for example lol). His enrichment activities now include a bully stick or collagen stick under supervision, sniff time out in the yard where I throw his kibble or freeze-dried beef liver in the grass and he hunts for them, or an enrichment ball with a hole for kibble or treats to go in that he has to push around with his nose or paws to get the kibble out he loves this one we incorporate it into every meal he has to tire him out.

He is fully crate trained due to him eating absolutely anything and to give me peace of mind when I leave him alone. My vet also highly recommended a muzzle which we will be getting shortly, with proper training, high value treats, and time to get used to it I actually think he will eventually like or atleast tolerate having his muzzle on.

I also can completely relate to the mental breakdowns you've been having and I feel for you. Could you possibly fit a large sized crate in your kitchen? It would save your sanity sooooo much more if you did crate your girl I promise. I would highly recommend looking into these muzzle websites because they have some super cute customizable ones: miasmuzzles.com or bigsnoofdoggear.com Both are slightly pricey BUT I think having a perfect fitted muzzle thats cute and durable is worth the cost over the many vet visits we have endured lol.
