That really isn’t how that works.
The US has declared that they won’t allow the international courts to get involved, but that doesn’t necessarily prevent those courts from disagreeing.
“Jurisdiction” is only a thing when a court answers to some higher authority who has limited what that court can do. Since the international courts theoretically don’t answer to the US government, they can make any ruling they like.
They’re unlikely to bother, since they probably won’t be in a position to enforce any ruling against typical foot soldiers, but they absolutely could if it came to that point

They could, but it would be a big mistake: https://en.wikipedia.org/wiki/American_Service-Members'_Protection_Act
You may have heard it called the, “Invade the Hague Act.”
