Lying, dishonesty, and falsehood all imply motive/intent, which is not likely the case when referring to LLM hallucinations. Another term is "making a mistake," but this also reinforces the similarities between humans and LLMs, and doesn't feel very accurate when talking about a technical machine. Sibling commenter correctly calls out the most similar human phenomenon: confabulation ("a memory error consisting of the production of fabricated, distorted, or misinterpreted memories about oneself or the world" per Wikipedia.)
