Squill?

I was playing an ARAM game earlier today (as Sivir, if anyone wanted to check) and when my teammate LeBlanc went on a killing spree her champion name in the chat wasn't LeBlanc, but Squill. Notice how when a champion goes on a spree their name appears in the chat in parenthesis? I know the summoner name was not Squill.

I would have photo evidence but I wasn't expecting it at all. I was wondering if anyone else saw it. Will edit if I get it again.

I do have some theories. Squill is a type of flower. Notice in Zed's teaser there were flower petals coming from his mask? Also, could this Squill/Deadeye/Jhin figure be a member of the Black Rose, the group LeBlanc is a part of?

I want to keep playing as LeBlanc just to see if Squill shows up but I don't own her :(

Anyway would be nice to hear your thoughts on this lol I hope I'm not the only one who saw this.
