That's where this has always gotten odd to me. There's obvious impersonation, sure, but what if this same actress wanted to e.g. be the Major in a new Ghost in the Shell dub? Is she responsible for making sure everyone who hires her very definitely isn't hiring her as a soundalike if she wants her work to get released?
I'm sure it would be fine in reality, but if saying "her" (when advertising an app you can have a conversation with) is enough to make this impersonation, then the same logic says she's barred from certain roles (or categories of role) because someone more famous got there first.
