If riot really cared about toxicity and not money
they would disable chat period because it can only lead to toxicity and "by the time you can mute someone its too late" shot to death by words. wounded for life by the random on a screen somewhere in the world. Also its solo que pings are completely fine Chinese teams do the same when they have imports they can understand. for competitive integrity and a non toxic game you would remove chat completely. For marketing a game you would create bots to ban everyone and have a "war on toxicity" kind of like the 'war on drugs". funny how both those went huh?
what are the uses for chat in solo que huh? its either to tell people to pay attention or to be toxic. We have every type of ping in the book if they really wanted to stop toxicity and make the game better they would remove chat and keep the pings sound familiar? COUGH HEARTHSTONE. Yet nobody talks shit in that game oh wait cuz you cant. Sure its not a team game but neither is solo que from the last time i checked and you also have 50 differnt pings which work perfectly well ask china.
