The term "hallucinate" may not be the best. However, if the context is a device generating a plausible sounding but non-existent scientific reference for a given claim it makes, some words more specific than "producing false information..." seem needed. These thing make assertions, some true, some false. Since they emulate human behavior, they say things that would tend to convince people of their assertions. So "anthropomorphism" is a complicated question.
