For me personally, there is only two applications of LLMs in programming:

• doing tasks I kinda know how to do, but don't want to properly learn (recent example: generate pgf plots from csv data in matplotlib. 90% boilerplate, I last had to do it 3 years ago and vaguely remember some pitfalls so can steer the LLM in that direction. Will probably never again have to do this, so not worth the extra couple hours to properly learn
• things I would ordinarily write a script for, but aren't worth automating because they won't come up in the future again (example: convert this Lua table to a Nix set)

Essentially, one-off things that you know how to check for correctness.
