Well, one of your most grave mistakes is taking other fictions as a reference for how Valoran magic and stuff works. Creative people aren't holding a worldwide annual meeting to discuss the standards of magic, ki, energy and other metaphysical stuff that should be used in every fiction. Base your arguments on the grounds given by LoL, not by other fictional works.

What we can know about Riven is based on her Lore (and her League Judgement, but it doesn't reveal anything new for this topic). Her Rune Blade is empowered with Noxian Sorcery, so it may give the sword control over wind... or not. We don't know.

What we DO know is the fact that Riven was a leader of an army troop and her lore depicts her as a fighter on open field. She got into an ambush, ignited an emergency flare and got Zaunite war machines as an answer, eradicating almost everyone. The point of exilement for Riven.

Why do I tell you that? Because details are now important. First, Timing: When did Riven left the battlefield? Before or after Yasuo ditched his guarding duty? We don't know, but it's important to know if you suspect Riven of doing it. Second, Location: Where was the Elder located, where has Riven's troops been? If the troops were never close to the Elder, then Riven had most likely no business with the Elder. Third, Motive: Riven believes the Noxian ideals in a way most Noxians don't do anymore. In the Judgement she encountered a small girl and ordered her troops to secure her because Noxian Might has nothing to do with killing innocent civilians for Riven. If she couldn't kill the small girl, why should she kill an Ionian Elder who, given that Yasuo had to guard him, seems to be defenseless, too?

Food for thought.
