Some people cannot use paypal due to country restrictions. Most people who cannot use paypal use something called Payoneer, a company that offers an US bank account with a routing number etc and a debit card that can be used to receive money and purchase.
Payoneer has something called "us payment service" which is like an invoice that allows a payoneer user to request money from another business for some sales or freelancing services that they've done.
Payoneer as stated above also provides a bank number and a routing number so that everyone from every country can receive money from US businesses.
It is possible to use Stripe with payoneer (if you use stripe for wordpress or online shirt websites etc), but I do not know if itch.io allows the collected payout to be transferred through stripe and onto the user's payoneer bank/Credit/debit account.
I have some money in my account, I initiated a payout but don't have paypal configured, only stripe, I hope that Stripe is an option for non-direct payments, if not then I might have to contact the support for a bank transfer or something of the sort.
Either way, I know that the itch.io team is doing their best and I hope that the bank transfer option will be available soon.
