LLM's when leaned on too heavily, have a tendency to destroy critical thought, or perhaps more accurately replace it.
It is similar to a spell checker, while spell checkers improve spelling in general, they do not improve a persons spelling ability. Instead acting as a crutch. No need to spell well when the machine will do it for you.
Some people really like expanding their thoughts via LLM prompt. Some so much it acts like a big crutch, no need to think coherently, the machine will do it for you. So they use the LLM for everything.
As a related tangent something is messed up in my web browser spell checker, it gives the red squiggles indicating a misspelling, but refuses to give suggested corrections. I would fix it but... My spelling ability has never been better than it is right now.
