If you're talking about one game where you hardly talked, then you're understanding the whole report system wrong. Reports and punishments for them take time to be carried out so it is more likely that you got reported in one (or more) of the games you played half a day ago or yesterday - that is if you were verbally abusing. Don't think that just because you got a notice/warning, after a match, that it only applies to your (one) latest game.
If you weren't verbally abusing your team mates games before then there is not a lot you can do besides not get reported for the next few months.
I received a notice mentioning that I haven't been leaving games for awhile and Riot thanked me. Almost all of the times I "left" were from DCes and games not loading up, connection problems, of course. A couple of times have been family emergencies
If you truly did nothing, then the report is meaningless. Did you get banned? if so then you did say toxic or spammy things. If there was a little bit of toxic behavior then that report will be used if you get reported more.
