I've yet to see an LLM response or an LLM generated diff that suggests removing or refactoring code. Every AI solution is additive; new functions, new abstractions added in every step. Increased complexity is all but baked into the system.

Software engineering jobs involve working in a much wider solution space - writing new code is but one intervention among many. I hope the people blindly following LLM advice realize their lack of attention to detail and "throw new code at it" attitude comes across as ignorant and foolish, not hyper-productive.

Ask for a refactor...

Ask for multiple refactors and their trade-offs

Add it as an option when you ask it and see what happens
