Amazon US Seller Account setup-Non US Resident

Are there any South Africans here with a US Amazon Seller Account? I have been going down a rabbit hole these past few weeks, trying to decide what is the best way to set up my Amazon seller account. Should I open an LLC? Or should I use my South African (Pty) Ltd? I will be following the online arbitrage model. I have been advised to use a company in my home country for simpler Tax purposes. But have also had an online call with a US Accountant that also assist with opening Amazon Seller accounts saying it’s better to open an LLC, Non US residents are not taxed. I will only be taxed when transferring funds from the US to South Africa. And also because my customers will mainly be Americans, and for ease if purchasing products online - with a US address and dealing with prep centers. If there are any South Africans here, I would love to hear how you have set up your Amazon Seller account? Any advice here woukd be greatly appreciated.
