Basically, in one of my games, I met this toxic guy. He blamed me saying "You're useless." For just failing one gank, so I basically stoped ganking his lane. Late game I just ignored him and not help him a single bit. He got mad and started getting more toxic, and I said "I'm useless so I can't help you."
P.S. He also stole 4 of my buff, without asking.
Sounds like your team had to deal with two trolls.
no....."fighting" him would be to mute him the moment he acted toxic to you and report him after game
saying "I'm useless so I can't help you" (1) tell him you are giving attention to his toxic behaviors (2) encourage him to be even more toxic because he now has your full attention (3) in some interpretations, the toxic troll can view that as an engagement/challenge and push the limits of his toxicity to you/team instead of becoming deflated because no one care or pay attention to his toxic trolling
