Gotta nip that shit in the bud. Polite response:
"Hey, this looks like it came straight out of the LLM. Can you do a cleanup pass before I continue reviewing?"
I don't, I clearly say that it is a lack of respect to want me to review code you didn't even bother to check yourself.
Review it yourself and come to me when you're sure you did your best to do it right the first time.
