Why would you dislike LLMs for 1?

I have my personal projects where every single line if authored by hand.

Still, I will ask LLMs for feedback or look for ideas when I have the feeling something could be rearchitected/improved but I don't see how.

More often than not, they fluke, but occasionally they will still provide valid feedback which otherwise I'd missed.

LLMs aren't just for the "lets dump large amounts of lower-level work" use case.
