New LeBlanc is missing a lot of animations
Which are standard for modern league champs.
IMO some of the most important are that she only has a single 'Idle' and no 'Run' variants to show when she is slowed, sped up, switching to combat. She also does not have a "Attack to Run" animation so there is no animated transition when you move between autos.
I would strongly recommend watching this video by exoLL which shows all the missing animations and compares to other modern champions:
