Yeah, but Lego is more creative with the design.
You mean "we" are more creative with design when it comes to Lego? All Lego has to do is get a Lego mini-figurine, design the mass-produce detail for it's body and that's it. Maybe the plastic hair will have an original piece for it but that's it.
Yes it's kinda creative with how they adapt buildings and vehicles from movies or TV series into lego but it's more of what we do with it than how they made it.
Just saying if it's a popular franchise with a pulse, Lego will likely turn it into lego. And Funko Pops have come to the point where they will make a Funko Pop of practically anything.
