I'm sure one can try, but copyright has all kinds of oddities and carve-outs that make this complicated. IANAL, but I'm fairly certain that, for example, if you tried putting in your content license "Free for all uses public and private, except academia, screw that ivory tower..." that's a sentiment you can express but universities are under no obligation legally to respect your wish to not have your work included in a course presentation on "wild things people put in licenses." Similarly, since the court has found that training an LLM on works is transformative, a license that says "You may use this for other things but not to train an LLM" couldn't be any more enforceable than a musician saying "You may listen to my work as a whole unit but God help you if I find out you sampled it into any of that awful 'rap music' I keep hearing about..."

The purpose of the copyright protections is to promote "sciences and useful arts," and the public utility of allowing academia to investigate all works(1) exceeds the benefits of letting authors declare their works unponderable to the academic community.

(1) And yet, textbooks are copyrighted and the copyright is honored; I'm not sure why the academic fair-use exception doesn't allow scholars to just copy around textbooks without paying their authors.
