The answer is no, I don't know how to extract SFX from LoL. I've tried a few times in the past to learn how but they usually just end up with me growing frustrated with the extremely poor/outdated guides I have to use. I have no idea if League still uses RAF files to store their data but I reckon it'll still be just as obnoxious to get at. The filename thing is unrelated to that issue. :P

If what you want is relatively old (as in, was in the game before the sound engine overhaul), you can find most of the SFX by SpectralCoding here. Some of them might be off-pitch, though (which was the reason I couldn't upload Infernal Nasus' or Yasuo's dance sound, for example).
