The IRS does not care about what structure you use, they only care about compliance. It is very useful to reframe your understanding of the IRS. They are not really adversaries, they will even help you set up this stuff even though they are aware it undermines their own name of revenue. Remember, its only Congress that cares and even then they are pretending. The perception of the IRS comes from most people's interaction with the IRS: retroactive enforcement of a penalty at the least convenient time. Leading cash-poor people to want to hide from the IRS, leading to greater vulnerability.

By reporting taxes to the IRS or filing reports to the Treasury (their parent agency), yes, it may seem counterintuitive that you are associating yourself with additional properties to the literal government. But that doesn't inherently create consequences to other branches of the government, judges, or private creditors, it also doesn't mean they those other parties get to know about it.

Finally, one last thing to remember, obfuscating the existence or movement of money is not illegal. Its another reason why the IRS doesn't care about anyone's convoluted structure of companies and trusts around the world, because they are not illegal and neither are most transactions between them. A money laundering charge, for example, requires an illicit origin of funds. So it can only be a tacked on charge after the government has discovered the origin and the origin was illicit. As such, using your own legally earned money post-tax money and sheltering it in a convoluted way garners no issue from the IRS. And if it earns a little bit, you can still report and pay taxes on it. Also, the new thing in this century is that you also don't need a bank account to hold liquid assets under these organization's names, therefore nuking the Treasury/FinCEN report of foreign bank accounts when that was part of the strategy.
