20 lp away from silver 1 promos and I get a troll

I'm finally close to getting gold. I didn't care much for it since I don't play league as much as I use to, but I still want it. I started my ranked climb ~ 2 months ago? I got to silver 2 which is my current highest ever, and I inched my way up to 80 lp today. In my game that I would have won so easily (I was Malph into 4 ad, and we also had a Teemo), I get a troll Ziggs. He was a special kind of troll to me. He didn't int right away, no. Instead, he decided he was going to spam nothing but ff and make fun of different mental illnesses (according to the enemy Darius, I muted Ziggs). He then decided to take it up a notch and feed. There goes my silver 1 promos, and I know I'm going to deal with trolls which I'm fine with, but I just want there to be some form of justification as to my teams lost lp. My team didn't deserve it, but here we are, 20 lp in the gutter. This is way too much to ask of Riot simply because it isn't possible, but I wish there was a way for Riot to refund lp in troll games. The only idea I have as to how they would do this automatically instead of having to review every single game reported, would to see which champion died where, when, how often, to who, and what they did in-between. Some sort of way to see if they were inting. I know this is a long shot, but maybe some of you genius's could think of a good idea; the league community always has good ideas for this kind of thing. Thanks for your time.
