He's 100% full of shit. You don't have to have a private lawyer to file criminal charges in Portugal. Only for civil. There are Proescutors that try criminal cases on behalf of the injured (like in the United States). Those courts are called "Specialised Jurisdictional" courts. They have a Constitutional justice system. So he's lying.

Also, you don't get free surgery or medical care in Portugal unless you're a national. Which he's not. They'd attempt to bill his Health Insurance and if they can't, they'd tell him to pay up. Shit isn't free. It gets paid for by taxes. Ralph doesn't pay tax in Portugal.
I don't believe for a second that he filed a police report. He fucks himself just as hard as he'd be trying to fuck Cog. All Cog has to do is file a complaint against him and tell the cops that Ralph is on a suspended sentence in the state of Virginia. All it'd take is a search and phone call to the Virginia DA's office to confirm, deport him, pull his visa, and have a squad car waiting for him when he landed back in the states. That's if, of course, the Virginia DA was so inclined to fuck with Ralph and has had enough. Which, who knows? But it'd be catastrophically stupid for him to roll the dice on that.
