A US LLC is only going to make it easier for you to take US transactions and payments, but that's about it. You'll still need a US Bank + address to make taking US checks easier, you'll still have to file US taxes even if it's mostly passing through to you personally, and you'll still need to pay for the filing and possibly an accountant to handle it for you. The business (LLC) will still owe taxes on US income from businesses, even if your personal income doesn't have to pay US taxes out of what you pay yourself. I'm not sure how you get around that.

If you're relying on a service like Stripe to collect payment, does this still apply?
Taxes are unavoidable if you are collecting them in the US.
