Fraud in the scientific world has generally taken the form of fabricated results, but I don't agree that the word has transitioned away from the common and legal meaning of deception in order to get a benefit. Even if it had though, I'd be perfectly comfortable calling this fraud in this discussion based on the common meaning of the word. Just because we're talking about a scientific context does not mean we need to…
I disagree with your implicit assertion regarding the common meaning of the term in this context. I believe that the term fraud as commonly used when discussing things in a scientific context has always (for at least my entire life) been taken to refer to knowingly and intentionally falsified research results (also falsified appointments, falsified affiliations, falsified authorships, etc). > deception in order to ge…
That said even in a scientific context I still disagree and your example at the end is a fine starting point. By comparison imagine one of the profs said told the others that their house was burgled. The others would probably be thinking that things like TVs or computers or money was stolen, and not that the thief simply stole all their spoons. That doesn't make having all your spoons stolen not burglary. Likewise the profs expect that the results or authorships are where the fraud occurred because those are the best places to extract value with fraud, not by avoiding the simple act of writing the paper with correct citations. That doesn't mean fraudulently using an LLM to hallucinate a paper from your (we'll suppose for sake of argument) actual results is any less fraudulent though, it's just an unexpected form of fraud.
Edit: I want to be clear that this is not my argument: "well he exhibited reckless disregard for his professional duties when he opted not to bother reading the citation section". I see other people making that argument, and I'm not sure if they're right or wrong that that's another reason why it is fraud, but I'm certain that we don't even need to reach that question.
My argument is that it is fraud to represent the paper as a scholarly work when you don't know that it is correct. It is not that you are taking a risk it might be wrong, it is that you are actively representing that you know it is correct and if you do not know that you are committing fraud even if it happens to be so. This is a case of intentional deception, the deception being the representation that this is scholarly work, not reckless disregard for the truth as to the accuracy of the citations.
