I watched the play a few times; there is no question that KLS was hit and knocked down (somewhat).
The question is one of embellishment (which I think she did).
Reminded me of the Stewie fall near the beginning of the championship game ; the ND guard gave her a pretty good shove and she fell in a heap, for which a foul was also called (which the announcers didn't particularly like, but agreed that it couldn't be ignored).
Hit? yes, the effect exaggerated a little bit? probably.
Should we establish a new terminology that differentiates a pure flop,
such as Mabrey's from an embellished knockdown?
