You've probably not infringed the copyright, only the court can decide though; if you were to be challenged by the rights holder.
I think there are lots of factors in your defence:
you're not selling it , your use is an example for education
I don't think you're reducing the market value for the original(s) in any way
you've not included substantial verbaitim sections of the original works , but I think you have used more than just facts and ideas (not sure though).
But add in some more quotes, flesh it out, and then try to sell it . . . each step weakens the 'fair use' defence.
This the the problem for the LLM, it can be used for many things, and if it has no filter or limit, then eventually the collective derived works might add up to commercial, substantial reuse, and might include enough to have copied a substantial portion of the original.
Very hard to determine I'd think. Each individual use might be fair, but did the LLM itself go too far at some point?
Copyright holder probably struggles to challenge the LLM on the basis of all the things infinite mokeys might use it for in future.
I think most lifeforms will have more pressing matters than wasting large amounts of time an energy blasting signals in to space for no reason, or listening to the sky.
Maybe those civilizations that waste more energy chasing aliens die off sooner due to wasting resources on sci-fi bullshit and ignoring their real problems at home.
I think it is in the drake equation effectively, it factors into the length of time that the civilization might send and receive detectable signals - It doesn't say why the Civilisation might collapse, but the planet becoming uninhabitable is surely one reason. On wikipedia for Drake Equation the Carl Sagan specification of L is in terms of the "fraction of planetary lifetime".
I think a missing factor might be how directional transmission and receiving is, if we can't broadcast to and listen to the whole sky equally then we might have a 1/r-cubed type issue with the chances of both listening and transmitting with enough strength/energy at the same time.
