Licensing is much much more limited than you seem to be thinking of it. For instance, you said explicitly you want a way to control your ideas. The only thing this can mean is a way to control who gets to use your ideas, or what they get to use them for. So if I express a political idea in a novel way or tell a funny joke or something I should be able to dictate who gets to repeat it, or in this case with LLMs who gets to summarise and describe it.
This kind of control is antithetical to the spirit of the internet and would be frankly evil if people were actually able to assert it. Luckily in most cases it's impossible, nobody can actually stop me from describing a movie to my friends or from reposting a meme. Just copying and reposting what you wrote verbatim is something we can probably agree is wrong, but that isn't what's up for questioning here. The idea I was actually replying to in the first place was that you can decide somebody can't read your ideas - even if they're public - just because you don't like them or you don't like what they will do with them. It is hard to think of a more egregious kind of 1984-style censorship, really.
There is a place for regulation of LLM companies, they are doing a lot of harm that I wish governments would effectively rein in. It would not be hard if the political will existed. But this idea of saying I should be able to "control my ideas" is way, way worse.
