What you're saying doesn't make sense. Nevis asset protection laws here are only relevant to the extent the trust gets sued. The LLC can get sued, of course, but it's not yours. If the trust gets sued and has been set up correctly, you won't be considered to be the UBO and Nevis laws will protect you.The US banks can report you under CRS as well, those that are pert of the CRS. That is why I would recommend to double check that.
I am not saying that you own LLC, I am saying that the Nevis asset protection laws would not apply to the US LLC. And if you are indicated yourself as the owner if the LLC in the bank, you are completely exposed to any attacks and do not benefit from any asset protection.
With regards to US banks reporting US LLCs UBOs for CRS, I have never seen that because US banks do not report CRS. If you use US banks in other jurisdictions, they might, but that's not what we're talking about here.
