No it is not my god i was waiting for someone to experience the same, its literally the game, either the client or the game but its not the servers either, so basically you're playing league normally and out of nowhere in one of your games you get like 190 ms 200 ms 300 ms and you can't fix it, its literally unfixable, i lost 2 games because of it it has happened to me twice, i was playing a match just an hour ago, got into the game. 90ms ping as usual, no spikes since I ALWAYS have ETHERNET cable PLUGGED in my compute, then 6 mins into the match i start getting high ping spikes and it never goes down, i restart the game, i close and reopen the client, I restart the internet, I disconnect and reconnect the internet, i turn it off, i turn my computer off and turn it on. There is literally no fix, so basically once you get this bug in ur game you are doomed to lose, worse is it can happen twice or even 3 times in a row and its just terrible luck.
