I don't know every Slavic language, but know a few. There are rules of transformation of sounds which can make -ph to become -f, or -p, while -v is very-very unlikely. And the fact that in some languages "v" can be pronounced as "f" before unvoiced is not really applicable here - it doesn't make "f" to become "v". I think it's just a randomly generated Slavic-looking name. The author is Chinese btw
