You don’t. Upon receiving a destruction order, a company can delete the trained model or not. If they do delete it, it’s all good. If they don’t delete it, they (hopefully)can’t get caught using it again without company-destroying fines. They can probably do some kind of recovery in most cases, but I doubt a judge would be very favorable to them if they’re caught disobeying such an unambiguous order.
