One of the factors going into determining fair use is whether the use is commercial. Another factor is the effect on the market of the original product. Non-attribution + commercial use + affecting the marketability of the original product (which is what LLMs do) seems unlikely to be considered fair use by any existing precedent. That being said IANAL.
