What are you supposed to do when your team gives your enemy laner 4 kills at the start of the game?

Ok so.... I was playing Yorick into a Renekton, which is a guaranteed loss of lane basically, but I still had a chance to play it safe and take objectives. We start up the game and the Yi wants to invade, my botlane and mid follow up, and they get first blood. They then overstay their welcome, trying to take the red buff while the enemy jungler and his botlane are still with him, I thinking they'd take first blood and leave didn't TP down. My laner (Renekton) had decided to leash his jungler as well and was botside with Rengar, he (while my team were trying to take red buff) picked them off one by one in a matter of (around) 10 seconds. So at this point I realise that I'm fighting a 4/0 renekton with a level one tiamat. I play it safe staying back and letting my ghouls farm while I stay at turret. Then Renekton reaches level 3, mind you I'm playing very passively and just reached level 2, he all ins me at this point and kills me in 3 seconds (I pulled slightly away from tower to get some more ghouls, I also took ghost so I had no hard escape). After that I died under turret twice more, with my jungler giving him 2 kills them self, resulting in a 9/0 Renekton at around the 7-8 minute mark. He all ins me once more I stall for as long as I can with my W and E, but I die and he takes turret. The rest of the game was a stomp, he could one shot whoever he damn well pleased and we couldn't shut him down, he was level 15 when our fed jinx was level 11. I admit I was tilted after my lane was ruined since there wasn't even a remote evenness in gold. However, for the future, what should or could I have done to prevent this/counteract my team feeding my laner (Renekton) massively?
