I think it’s a big misunderstanding to say that Kathleen Kennedy put that scene in the film but I’ve seen a few people suggest that. What Rian said was that Kathleen was interested in seeing Leia show force powers, it’s a stretch to believe that Kathy decided how they should be shown. She would leave the writing to the writer.
That section of the interview starts at about 19:20.
But that doesn’t fit into the “Star Wars sucks because of Kathleen Kennedy” narrative.
