When Kai'Sa is an ally to Vex, she observes a little drop in her full damage output. This difference could signal that Vex does not provide cover for her to deal more damage or that their support also helps extend the game's duration. Similarly, when Kai'Sa is played together with Vex on the same side, he usually scores many fewer killing sprees than when she plays without Vex. This is contrasting evidence that she is worse when playing with Vex.
Moreover, when Kai'Sa plays with Vex on the same team, she on average takes a little less damage than when she plays alone. Taking not as much damage could mean that Vex does a decent job of covering Kai'Sa during teamfights.
