Hey so I'm currently working for a US LLC and I'm exploring some payment options, since receiving a wire transfer in my country is a hassle. Say I open a US bank account and receive money, would I pay tax and how much? Would my employer pay taxes? I'm not a US citizen and I don't live there, so I'd be spending all my money abroad.
Given that receiving a wire transfer is "a hassle" I assume that either the LLC you're working for is rather small/new, or the country you're working in has few (economic) ties to the US.
You could go old school and use a service like Western Union (which has a fairly large world-wide presence). Some more modern equivalents are PayPal, Transferwise, MoneyGram, OFX, etc. (no endorsement given or implied). Or you could go very modern and use Bitcoin (or BitcoinCash, Litecoin, Ethereum, ... if the fees are too high) as one of their raison d'êtres is borderless transfer of value (though you might want to convert back into your local currency quickly to avoid the volatility).
I'm pretty sure the manner in which your paid has no bearing on who (between the US and your home country) is going to claim taxes on it, unless the presence of a bank account is used as evidence in a residency test. The advantage of a US bank account is that you could decouple the payment from the transfer (e.g. get paid weekly but only deal with wire transfer hassle on an as-needed basis, and you might have more visibility/control in the process if you own both ends).
