Can somebody explain to me why I cannot remake this game ?

Our ekko didn't move, didn't buy, didnt do anything for the whole duration of the game as you can see in the ss. I know the system automatically marks you as AFK if you do not leave the fountain after around 3 min, so why does riot consider it is ok not to remake this game, while it's perfectly fine for the other team to play against 4 players, and call it a "COMPETITIVE RANKED MATCH" It's really beyond my understanding, it's not the first time it happens, I made a ticket about a similar situation in the past and in short support said it's a feature not a bug and these are the rules. Amazing.
