What I prefer is interfaces that are more systematic and based on comprehensible principles. Like, for search (as someone mentioned in another comment), I want to be able to search for pages (or records, or whatever) that contain the text I searched for. I don't want an interface that tries to understand what I mean, I just want it to use the data I give it in a way that's deterministic enough that I can figure out how to make it do what I want.
In my opinion, the best applications of LLM UX will have full clarity for the end user (something we're trying to do with MatterRank). The non-determinism should be something the user can control to get better results, not something the engineer has prompted that takes control away from the user.
Now, if the use case you're looking for is "give me results with x text", then yes I agree with you that LLMs are just getting in the way. But that's not always the case.
