I'd suggest that everything output by an LLM is a hallucination, but it often enough hallucinates something that resembles reality.
If you're going to be that loose with your definition of hallucination, I'd really hope you apply it to yourself. That's a level of introspection that you need to avoid letting biases that all of us have deep down end up affecting your higher order function.
We humans rely on a ball of biases, interpolations and extrapolations to function, LLMs don't have a monopoly on that.
