You're right, she doesn't think.The problem with Lou is that she never actually stops and thinks of the consequences of her actions before she does and says things.
But she also gets cocky, it started with thinking she had one up on Blueskies, because that James and the giant peach found out some information. That then made her feel she was "winning" and then her mouth ran away from her, thinking she can do and say as she pleases with no consequence.
I can imagine the snivelling mess she'll be if/when this causes a backfire and rightfully so, with other creators. Even though SHE said those words, I guarantee it'll be someone else's fault, more than likely, the "lovelies"
