USA always relies on their serve so much... it's a very unpopular opinion but I rarely find them an interesting team to watch because of that.
They even had 6 rotations of jump serve before in 2018 WCH.
A bit offtopic but i remember in the crucial group match against Argentina during Tokyo Olympic, their serves betrayed them so hard... probably the pressure of losing getting to their head and they kept serving fault balls from the start to the end of the match. They made tons of serving errors in that match and got eliminated.
