I've run CTF games at major conferences. The point is to solve the challenges by any means necessary within the rules... and that which is not forbidden is allowed.
If I, as a person running a CTF, did not want my players to do this, I would set up a few problems which would have incorrect (but not obviously so) "solutions" generated when fed to LLM.
The Shamir's Secret Sharing reminds me of the time I was playing DEF CON CTF Quals, and had the bright idea to try to scan for challenges. I found one - it involved hiding fragments of a split secret in a modified version of ADVENT. I solved it. Even when the board was fully opened, it was nowhere to be seen. You does your hacks and you takes your chances...

The thing I found was not one of the 25 problems.
