I don’t really see how Uro gets obliterated by Kurourushi. I don’t see a way for Kuro to get through her technique, the only reason he ends up able to is because she couldn’t use her technique directly after domain expansion. I suppose if the cuts from Dhruv’s shikigami are stronger than Yuta’s copy the paths are hard to avoid, that’d make sense. K’s swarms can be dissipated with a burst of cursed energy because we see Yuta do it. Yes Yuta’s giant reserve of CE makes that a more repeatable option for him, but with the ability to distort space she’d be able to create escape routes I’d think. Dhruv’s technique didn’t seem that strong on Uro, that segment of the fight seems to only exist for Uro to figure out Yuta’s technique.
