Yes. Unless something useful is actually added by the commenter or the post is about, "I asked llm x and it said y (that was unexpected)".
I have a coworker who does this somewhat often and... I always just feel like saying well that is great but what do you think? What is your opinion?
At the very least the copy paster should read what the llm says, interpret it, fact check it, then write their own response.
I keep this link handy to send to such coworkers/people:

I have a client who does this — pastes it into text messages! as if it will help me solve the problem they are asking me to solve — and I'm like "that's great I won't be reading it". You have to push back.

then write their own response using an AI to improve the quality of the response? the implication here is that an AI user is going to do some research when using the AI was their research. to do the "fact check" as you suggest would mean doing actual work, and clearly that's not something the user is up for indicated by use of the AI.
so, to me, your suggestion is fantasy level thinking
