I'm very certain that this is not fraud, across multiple legal systems, both roman and common law. In both cases fraud requires a person is deprived of a material good. Neither the defrauded person or their material loss is present in this case. Maybe there is a oddball legal system somewhere in the world where fraud is something entirely different, but i doubt it. "Fraud", just like "Decorator Pattern" is a well established concept and pretty simple concept, even if there are edge cases. This does not fit at all.
In academia this is miss-attribution, outside of academia this does not exist.
This is clearly not not copyright infringement either as LLMs do not claim copyright, nor could they. Just like the photograph taken by the monkey, or pictures drawn by crows. LLM output is not a creative work either.
If this is unethical or immoral is a totaly different question. I really dont think so and I dont think you argue that position well.
It is misrepresentation for gain, that gain does not need to be monetary to be material. For example, it can be reputational.
It also is copyright infringement, because what the LLM “generates” are actually portions of its training set, which were covered by copyright. Just passing through an LLM does not remove that copyright from that work.
In German and French (roman) legal systems this is a "Vermögensdelikt", and explicitly about material damage and gain. Yes, common law can be more broad (in canada it isn't really, it just also includes service, btw.), and yet it clearly does not meet the definition, as there is a damaged/defraued party and fraudulent/gaining party. We are not talking about somebody usurping somebody else reputation, after all.
You misuse a technical term that is well established since antiquity.
You do not know what this word means. If you want to argue about semantics, look up the definition. This works especially well for legal terms as laws define them.
(That said, IANAL and there are very many different legal systems and I am not ruling out there exists one that is competently different - laws can be changed a will, after all.)
It is also obviously not copyright infringement, because this is simply not how copyright works, at all. I cannot and will explain of all copyright here. Instead I will point this out: Every code produced by a human who read copyrighted code would fall under your definition.
