Having Constant League of Legends Update Notifications Despite No Installation

I'm encountering an infuriating issue with the Riot client. Even though I haven't installed League of Legends, the Riot client keeps bothering me with update notifications. I've looked through my computer for any files related to League of Legends, but unfortunately, I couldn't find any. Exclusively utilizing the Riot client for Valorant, I find it rather insistent on updating LoL, despite my efforts to disable auto-updates. Is there a way to get rid of these annoying update notifications from the client, even though I don't have LoL installed?
