The stats shown on this page clarify some important LeBlanc versus Senna matchup stats that can help us figure out the distinctions between the two. As an example, LeBlanc’s KDA ratio ([kills + assists] / deaths) of NaN is better than Senna’s ratio of NaN, showing that LeBlanc may be more central to her team's team fighting potential than Senna. This observation is largely a result of the difference in kills.
LeBlanc usually has a slightly larger longest kill spree than her enemy does. Commonly, she receives more damage than Senna. This commonly reflects different amounts of tankyness; however, it can also illustrate that the champion with increased HP has less mobility and thus is not able to kite away from additional harm when poked or engaged.
Both LoL champs are great champions. Both have their strengths, weaknesses, and counters. In League's current meta, LeBlanc usually loses when taking on Senna, with a 46.6% win rate. As a result, LeBlanc makes a poor counter for Senna.
While LeBlanc does have a lower win rate than Senna, when facing one another, LeBlanc also has a greater difficulty level that makes her a more difficult champ to pick up and master. You may get destroyed when picking LeBlanc into Sennaas her relative depth means you may not be able to unleash her full potential without a significant amount of practice beforehand.
Additionally, LeBlanc also has almost no amount of CC and other utility, a similar amount to Senna. This makes her just as valuable during teamfights, especially when trying to counter champions with a lot of burst damage.
While there is not one best champion in League of Legends, in LeBlanc vs Senna matchups, Senna is the better champ with a much lower win rate, more champion depth, and a similar amount of utility to help out your allies during teamfights.

LeBlanc typically gets more CS relative to Senna. Champions who typically don't earn much CS typically don't require much CS to be effective, such as supports. They are able to scale properly off of their skills, stats, and first items alone. Yet, champs with large amounts of CS, such as hyper-carries, often require several high cost items to be effective. In either case, try to do better than the values shown on this page to do well.

When LeBlanc bought at least these three pieces in her build, she performed significantly better against Senna than with many other commonly used builds. In fact, LeBlanc had an average winrate of 46.6% when countering Senna with these items in her kit.
