Nah. So far we haven't hit Iran's oil export infrastructure. If China makes a serious move we blow it up. We can also close the straight ourselves and claim it's for protection.
I ain't reading all that, but if you're referring to the strike on the oil storage facility in Tehran, AFAICT that's not for export. It's local consumption. We haven't, to my knowledge, hit oil exports yet.
I don't think oil works like that. Infra takes a long time to reroute, especially in war time. Exports are nearly all of Iran's economy. They can't turn it off or they starve.
