I didn't have the words to articulate some of my frustrations, but I think you summed it up nicely.
For example, there's been many times when they take it too literally instead of looking at the totality of the context and what was written. I'm not an LLM, so I don't have perfect grasp on every vocab term for every domain and it feels especially pandering when they repeat back the wrong word but put it in quotes or bold instead of simply asking if I meant something else.
