> if it happens the rep will probably be laughed out of that courtroom right into a jail cell if they don't try to defect The US does not jail representatives of enemy nations as a matter of course. There is a North Korean representative in New York (to the UN) and they are not being arrested and thrown in jail. As long as they follow the local laws, I expect that any other representative (like a hypothetical one that wants to sue for alleged copyright infringement) would be similarly protected by the law.
