as long as it comes from a 100% legally trained model

This is where your entire argument falls apart. You can't sue people just for using a tool that has the capability to violate copyright: you actually have to prove they did so. While it's technically true that you don't need to meet the bar of "proof" for civil cases, you're still not in luck: the bar is "preponderance of evidence," which you don't have if you're just blindly suing people based on using an LLM (and zero actual evidence of infringement). Using an LLM isn't illegal, so evidence that they used an LLM isn't evidence of anything that matters to your case: aka, you have nothing.

All of your other examples similarly fall apart. For Napster cases, the RIAA had to show people actually violated copyright, not that they just had Napster installed or used it for non-copyrighted works. And again, you're trying to motte-and-bailey your way out of your original claim that you could blindly sue LLM users, as opposed to training companies who make the models. You couldn't sue Megaupload users who used Megaupload for random file storage — you could only sue Megaupload for knowingly not complying with copyright law.

You really just don't understand the legal system. I'm not going to respond to this thread anymore. If you think you have a free money cheat code, go ahead and try to use it — you'll fail.
