It's not enough to simply get a bunch of reports. If you get consistently reported over time across multiple games, THEN the automated Tribunal system will open up a case on you. But that alone won't be enough to get you banned.
Rather, once a tribunal case is opened, a majority of PLENTY of anonymous people, who will look at your case anonymously, (they won't be able to see which summoner names, levels, etc anyone has) and then decide if your behavior was toxic enough to warrant punishment.
From what it sounds like, you did nothing actually wrong: you didn't insult the others in the game, resort to crude language in a derogatory manner, intentionally feed in an obvious manner, spam, or do anything like that. As an added bonus, everyone else DID do at least one of those offensive things. So odds are very much in your favor you'll be seen as completely in the clear.
However, if the other player that tried to get you banned happened to act like that repeatedly, then they will get reported in many of those games, and a Tribunal case for THEM will be opened... And how do you think the Tribunal participants will react when they look and see his abusive chat messages?
