When people are autofilled is there any MMR consideration? These games are not fun.

Just had 3/5 people autofilled in my plat2 ranked game and we just opened at 8 minutes because it was obviously over.

Now, this loss was partially my fault because I op.gg'd them all and I knew I had ppl not in their main roles and I still played the game.

As I write this I am seeing the irony that my "fault" in this is playing LoL knowing that this is a thing that decides game outcome.
