It seems unlikely to me. The same rules prohibiting soliciting unregistered products that prevent them from opening an account for a US individual also apply to US LLCs, unless you have $100MM (I think) to be a QIB. I think you'd have a better shot starting a foreign LLC, but then you'd have to deal with PFIC laws.
I see. I was looking at trading permissions because the options are limited to what the US allows - Italian stock futures is actually a choice oddly enough but there are only a few of them; in general Euro stocks but no options or futures are available. No CFDs of any kind. So I guess politics keeps a fair bit of the world's products closed off from us.
SPYS are off limits to residents of most EU countries. Protests to the contrary it is protectionism for European financial industry not the nonsense that it exists to protect European public.
It's not politics, it's just U.S. law that requires you be registered in the U.S. to offer securities to U.S. citizens and has for decades. The European exchanges have the option to request a no-action letter as some have. Obviously those who haven't see the amount of work involved as not worth the benefit. There's a good older thread that explains all this, https://www.elitetrader.com/et/thre...-trade-foreign-equity-or-index-options.99451/
Lucky for you, I do not believe being polite requires too much effort. Otherwise I could have called you a numbnut for this answer. SPYS are not off limits to EU residents. It just requires a minimum amount of capital.
