what should a solo player do when

What should someone who plays in solo que do when the entire team is toxic? For example I was just in a match where everyone was a "random" and it started off fine. We had some weird champion picks but I'm not bothered by those. I don't THINK the others were either, but before 15 minutes had past the negativity had started flying from everywhere. I tried to reason with everyone by suggesting strategic advice and offering support to the ones who were seeming to have a bad game, but at what point should I just mute everyone? That seems like it won't benefit anyone. Should I report everyone for arguing amongst the team and calling each other "bronze" and such? There are just too many players who are toxic in this community its ridiculous.
