Troll picks and feed int before matches

Just had to dodge a game because 1 of the 5 of us had already decided to feed during champ select and had a troll pick in jungle. After that 2 others decided to troll pick and express their int to feed also because of his pick. So like.....why is it I have to take the dodge and take the LP hit? what am I supposed to do you know like holy crap. I'm supposed to be stuck at (Insert rank here) forever? because i have to dodge and take huge LP hits before a game begins or have a crap game someone int feeds the whole time and lose even more LP? what then i report them?? I've already lost my game, i've lost my promos, i've lossed my lead ect. just checking others thoughts on this as well.
