But yasuo doesn't have mana, what would giving his abilities mana costs do? Would he be able to cast them infinitely anyway, because the null value breaks the game, would his abilities drain his flow, or would he just be unable to use any abilites?

You need to think of these things. It's such a dramatic oversight to give mana costs to a champion without mana, no wonder why Riot doesn't do it.
