Well, first of all, he and Dinwiddie are tied for the second-most field goals on the team - he's not averaging the second-most, by himself. Given that Dinwiddie's minutes are still being managed, he's averaging more when they're both on the floor together. And field goal attempts is an oversimplification of how the options are ranked, particularly since it doesn't take into account free-throw attempts.
Take for instance:
Trez: 18.4 points on 10 FG attempts and 6.3 FT attempts; 48 touches per game.
Kuzma: 14.8 points on 13 FG attempts and 2.1 FT attempts; 46 touches per game.
While Kuzma is averaging more FG attempts, they both actually have relatively the same amount of scoring possessions when taking into account FT, but where Trez has the advantage over Kuzma is, he's the go-to frontcourt option, whereas Kuzma has to compete with perimeter touches with Beal and Dinwiddie. Furthermore, Dinwiddie runs the offense, handles the ball the most, and he typically is second to Beal in closing. There maybe instances where Kuzma has the hot hand and is fed the ball (like against the Cavs), but that's not a reflection of his standing in the offense.
He has a 53 TS% (which takes into account all his field goal attempts, both twos and threes, and also FT), which is identical to his TS% he had in 2019/20 (which was/is the lowest of his career). If you want to be pedantic, he's having equally the most inefficient season of his career. And no, you can't just remove a game just because he shot badly in it. You can't just remove roughly 10% of the sample size.
This is your problem, you manipulate shyt to make your arguments, just as your whole agenda here is to protect Kobe. And don't play dumb by getting me to spell it out to you.
