Not all llm errors are hallucinations - if an llm tells me that 3 + 5 is 7, It's just wrong. If it tells me that the source for 3 + 5 being 7 is a seminal paper entitled "On the relative accuracy of summing numbers to a region +-1 from the fourth prime", we would call that a hallucination. In modern parlance " hallucination" has become a term of art to represent a particular class of error that llms are prone to. (Others have argued that "confabulation" would be more accurate, but it hasn't really caught on.)
It's perfectly normal to repurpose terms and anthropomorphizations to represent aspects of the world or systems that we create. You're welcome to try to introduce other terms that don't include any anthropomorphization, but saying it's "just wrong" conveys less information and isn't as useful.
