Which Riot game studio title does Wikipedia say Valorant's developer is behind?

League of Legends is the Riot Games title that Wikipedia identifies as being behind Valorant’s developer. Riot Games developed and published League of Legends before creating its tactical shooter, making the two games part of the same studio’s history.

Riot was founded in 2006 by Brandon Beck and Marc Merrill, and League of Legends became its breakthrough release in 2009. The multiplayer online battle arena helped establish Riot as a major free-to-play developer and later publisher. Valorant expanded that portfolio into a first-person tactical shooter, combining precise gunplay with character abilities.

The wording can cause confusion because Fortnite, Apex Legends, and Overwatch are also prominent multiplayer games, but none is a Riot Games title. Fortnite is associated with Epic Games, Apex Legends with Respawn Entertainment and Electronic Arts, and Overwatch with Blizzard Entertainment. League of Legends is therefore the single canonical answer, not merely a game with a similar competitive audience.
