While they will agree with you that they don't, it's also the case that this is via training.

Consider that we have recordings of Brent Spiner covered in white paint and wearing yellow contact lenses claiming to have no emotions, not because he didn't, but because he was playing a role, which is also something we know LLMs can do.

So we don't know for sure if LLMs do or don't have qualia, irregardless of what they say, and won't until we have a more concrete idea of what the mechanism is behind that sense of the phrase "mental state" so we can test for their presence or absence.
