Will my LP be dropped because of trolls in ranked?

First 5 minutes into the game top, mid and jg died 6 times in total.

Yasuo was flaming in chat saying "why do i even expect anything from you guys" then died 4 times in a row,

Jg nunu who's 0/5 now after 7 minutes said "yas ur trash" and the yasuo disconnects.

We obviously lost that easily, after 10 minutes our team was doing decent except nunu was 0/9 and yas DC'd

I can't believe people treat ranked like its a joke
