This should really be a point where academia has to change. The AI genie can't go back into the bottle.
No more papers. No more essays. No more homework. Everything needs to be proctored. Grades should only be able to be earned during class hours, at university testing centers, or university computer labs on monitored computers. AI tools used to detect AI usage will hallucinate just as much as any other AI, so this is the only way to protect honest students and make dishonest ones more honest.
