Nope... No one uttered that line at all in TLJ.. Why keep a 40 year old, 8 movie tradition going?? Rian wants everything his way, and Kennedy is on board with her boy & yes man. Oh, Disney, so sad....
The Wilhelm scream is something many directors have done as a homage to film as it's been used since it's 1st recording in 1951. It's a tradition. Many directors insert it to keep the tradition going. Rian Johnson doesn't follow tradition. He's above that and better than all the directors that have come before him. I guess your not really a film fan if you think it's stupid. My son once noticed it and asked me and I told him the story behind the sound. He now looks for it in every action movie we/he watches. It's a fun easter egg. Sorry you don't approve, especially since you actually think TLJ is a fun movie.
And yes, it is in RO.... "There is a 'Wilhelm Scream' found at the start of the Rebel Attack on Jedha. A grenade is thrown in front of the armored transport, followed by a number of Stormtroopers being shot (timestamp 00:31:20). During that initial gunfight you can hear the start of the classic 'Wilhelm Scream' but cut short by gunfire." Gareth Edwards actually cared enough to keep the tradition going.
It's just another warm and comfortable feeling.
