The Olaf Kai'Sa synergy stats shown here demonstrate the areas of his gameplay that do better (or worse) when paired with Kai'Sa, compared to his overall stats. Significant differences are areas of focus that highlight how his gameplay changes when paired with this other champion.
Overall, Olaf sees a very large drop in his KDA (ratio of kills and assists to deaths) when paired with Kai'Sa. His KDA decreased from NaN to NaN. This worsening shows that Kai'Sa helps Olaf perform not as well in competitive League matches. Yet, the small difference demonstrates that this performance change is not very impactful.
When Olaf is an ally to Kai'Sa, he gets a little decrease in his full damage dealt. This may demonstrate that Kai'Sa does not help cover for him to dish out more damage or that her presence on the team also helps increase the game's duration. Similarly, when Olaf is played together with Kai'Sa on the same team, he usually scores many fewer killing sprees than when he plays alone. This is contrasting evidence that he is worse when playing alongside Kai'Sa.
Moreover, when Olaf plays with Kai'Sa on the same team, he on average receives a little less damage than when he fights alone. Getting dealt not as much damage may indicate that Kai'Sa does a decent job of protecting Olaf during team fights.
There is no universally accepted best companion for Olaf that will 100% of the time be his top teammate. However, Kai'Sa is a very bad teammate for Olaf. By locking into the same side as Olaf, she drops their win rate by -3.6% to 45.4%. This demonstrates that there is an easy to overcome and exploit synergy between Olaf and Kai'Sa that allows them to perform worse together than alone.
Kai'Sa has a greater difficulty than Olaf. That means you must be cautious when enlisting Kai'Sa allies to play with, as they will need a greater level of skill to do well with you.
Playing together, Olaf players should expect to witness an overall large increase in your team’s ability to destroy wih physical damage. Together, these two can provide a great amount of sustained physical damage.
In contrast, by bringing Olaf and Kai'Sa together, you may not be providing your side a great deal of crowd control. Make sure to bring other champions on your team that neutralizes this relative gap in this pairing's potential.
Regardless of your Kai'Sa ally's ability, you need to focus on maximizing your income, outlasting your enemies, and clearing objectives. If you do this, you should do well, regardless.
