Are we allowed to extract champion SFX (such as abilities SFX)?

I apologize in advance if such a topic has already been created before. I didn't look for any. Please, post me a link to it, if it exists. Recently i've found some SFX extracted from the game, that are not a Wikia resource or something like that. In my case it was Odyssey Sona SFX (her abilities, auto attacks sounds, idle music, etc.). I really liked them and i wanted to use one as my notification sound for my phone. Am i allowed to do that? Or does it interfere with the terms of usage? Would i be allowed to use these SFX on web design (for example, as a Twitch follower alarm sound) if i credit where the sound is from?
