I find LLMs to be most useful for me as a StackOverflow replacement. I ask questions in a generic way, and adapt the answer to my specific problem manually. I don't do agentic coding, and I usually avoid directly using AI generated code unless the problem I am having it solve is a mechanical transformation (I am giving it all the knowledge it needs to do what it needs to do), or something that is low complexity but depends on knowledge that I don't have.

You might as well ask an accountant why he/she uses a calculator. I really don't think you're asking the right questions here. These questions will lead to obvious answers that you don't need to interview people for.
