Howabout: lied. The LLM lied indirectly (perhaps) but it made a claim that was false. Which is a lie.

Humans lie and LLMs “hallucinate”? What gives. It’s an untruth that the LLM is selling for a truth, that’s lying in my books.

And since we don’t know how or why the LLM works, we can’t even judge whether it explicitly lied or only because it didn’t know better.
