How to start a US subsidiary of a small french e-commerce business ?

I don’t know if that scenario is doable on a very small budget, and if it is, I don’t know what are the implications, how to create a subsidiary in the US, if I can do it as a sole proprietorship, where I will be taxed, what I’ll need to think about, etc.

(I want to sell on Amazon.com (US marketplace) while living in France and the only way to get liability insurance in that situation is to create a US company. I still need a french company to have a status in France).

I come here because the professionnals I contacted tell me to go ask someone else every time. It's pretty frustrating.

Thank to anyone willing to help.
