> IME using LLMs for software development corrodes my intuitive understanding of an enterprise codebase.

I feel you there, I definitely notice that. I find I can output high quality software with it (if I control the design and planning, and iterate), but I lack that intuitive feel I get about how it all works in practice. Especially noticeable when debugging; I have fewer "Oh! I bet I know what is going on!" eureka moments.
