To me it sounds pretty damning. "The tool hallucinates" makes me think it's completely out of touch with reality, spouting nonsense. While "It has made a mistake, it is factually incorrect" would apply to many of my comments if taken very literally.
Webster definition: "a sensory perception (such as a visual image or a sound) that occurs in the absence of an actual external stimulus and usually arises from neurological disturbance (such as that associated with delirium tremens, schizophrenia, Parkinson's disease, or narcolepsy) or in response to drugs (such as LSD or phencyclidine)".
I would fire with prejudice any marketing department that associated our product with "delirium tremens, schizophrenia, [...] LSD or phencyclidine".
