What am I supposed to do?

So, I finally get to play my first ranked game in season 9. I have a 12 week old son, so my time has been limited. I get in to champ select and our adc starts spamming a twitch channel. Mid hovers Yasuo and adc bans Yasuo. He then proceeds to say we care about elo more than him. Mid locks ghost/cleanse Janna and adc locks Teemo. Now I'm stuck. Do I dodge and get dinged for leaving queue or do I let the game load where I'm forced to get trolled by players until we finally lose? This is so infuriating. Please, Riot, help me understand what my best course of action is in these moments.
