It doesn't work like that, Itch has you send you the money. PayPal can't possibly know about them at this point. Either way, you're not being ignored, there must be some mistake.
Yes, if PayPal somehow knew Itch has money to send you. Which they can't know because it's not like you sent Itch an invoice or anything. So you most likely have to resolve the issue with Itch support, because far as PayPal is concerned that money doesn't even exist yet.
