Steam is still accessible in Russia btw. Sometimes it's spotty, but it's because of Russia's own restrictions, Valve itself is happy to keep doing business there.

Does Valve just have an internal Russian entity that processes with a domestic payment processor, then?

All of the international payment processors (ie, anyone piggybacking off Visanet) are in compliance with the sanctions.
