“There is no reasoning, no truth, no falsehood, no lies” etc is as close as it gets to the actual definition of “bullshit” used here.

I agree with you about anthropomorphizing terms like “hallucinating” and “lies”, which imply belief, intent, or knowledge in a human sense.

“Bullshit”, as used here, is a perfect term to describe LLM output specifically because it indicates that none of those terms and concepts apply.
