So I got banned for scripting what the hell Riot?

Before you guys flame me for "being a hacker that just wants to cry" I need to tell you I don't even play this game, let alone hack on it. I barely have 20 hours in the last 2 years probably. I decided to play a few matches this summer after a long year+ break. Everything was fine. I was still a noob not winning anything. I was on a scholarship over the summer in Finland and I was playing with my roommate. The scholarship ended, I came home and didn't touch LoL anymore as it's not one of the games I play anymore. Then 1.5 months later, I get an email for being perma banned for scripting?

From what I read on the Riot official stance on hacking, perma-banning someone is done in cases where scripting was used almost all the time and helped a significant amount. "up to a permanent suspension for consistent, blatant use." is what you guys say in there. I don't even play the game, not even 1 hour a month, how can I consistently and blatantly use anything for that matter? What the hell Riot I barely played 15 matches in 1 year let alone scripted them? I have not been ranked for 2-3 seasons now. I have absolutely no intention of ever hacking/scripting/cheating in a game where I don't even play??

What can I do really? It says I am permanently banned but there surely is a way to remove this right? I was not hacked. My password is still the same, still has been for almost 5 years. I made this account so long ago I can't even remember how old I was.

I have never ever been banned in a game for hacking before. I never even knew there were hacks for League until I got banned and asked my friends how could you even hack in here?

EDIT: Apparently there is a website where another user helped me and found a match history of someone in my account, playing when I shouldn't be playing at all... https://matchhistory.eune.leagueoflegends.com/en/#match-history/EUN1/28822931 Can I get my account back as it's clear I was NOT hacking and got my password somehow stolen?
