There's probably an answer right in front of me that I'm missing, but why do the Len players seem to air dodge so much? Are they randomly doing it or is there a point?
Air dodging accomplishes a couple things for hlen.
Air dodge can turn you around when you end up on the other side of the opponent at the end of the air dodge, which allows for some crossup shenanigans.
More importantly, len falls like a brick, and air dodging keeps her in midair longer to abuse her air normals and j.236a.
There's a couple of tricks with it too, like iad backwards > air dodge > j.236a will cover most of the screens length faster than back dashing on the ground, which can be useful for setting up black cats, or just creating space in some matchups.
