Trolls in prelobby ranked.

Ok, so im a low elo. Just silver 4, but more and more I see trolls in pre game lobby to ranked matches. Trolls that initiate alot of pre game "rage" if you will. Trolls that talk smack on purpose, last picks that don't want whatever role may be left, or even the people like my last lobby where first pick took mid and 3rd pick CALLED mid, third pick still auto locked in another mid player and we ended with me last pick which was either no adc, or no support and chances are with them "Arguing" over mid 90% of the time they BOTH end up going mid and fighting more leaving bot short a player. I've been dodging lobbies more and more lobbies but afraid im going to end up banned very soon, because in my opinion I'd rather dodge and lose 2 lp than get into a rage educed, unbalanced team game where everyone fights and argues and then I lost 20+ lp anyways, 15-20 minutes of my life arguing in a game I knew was going bad in pre lobby, and all 5 of my team are pissed to the max going into the next lobby possibly educing more rage into 5 other possibly lobbies. Yes, I could just deal with it and go into the match and ignore everything but it still AFFECTS me as I would have ended up the short end of the stick. I'm not sure if anything at all could be done about this but maybe a bit of constructive thought here? I feel like with all the AFK matches, the raging feeder matches, the arguing with a teammate who is mad and only wants to solo push lanes while your team gets outnumbered every time and crunched 4 v 5, that by now I could easily be gold considering I've been up in silver 1 at least twice. My whole point to this is it takes ONE person to ruin an entire game, that one troll affects 4 others attitudes going into the game which usually also affects their playing and holds everyone back. Really what's the better choice here, dodge and be banned or just play with them and be affected over all? Im not the golden boy of the realm that's without a doubt but I have personally let someone else affect me and everyone who's been in that position MULTIPLE times can agree, it's very hard to ignore after multiple times.
