You,re wrong. He takes 2 dribbles and jumps off his left foot. A text book jump stop. The rule for ending the dribble means he stopped rather than jumping. Either you're wrong or jump stops have been improperly called forever.
For him to pivot after the jump stop, he needs to end his dribble after he jumps off his left foot.
From https://en.wikipedia.org/wiki/Traveling_(basketball), I'm highlighting what happened in bold. If Trevion were to be judged that he ended his dribble in mid-air after the hop off the left foot, then he can pivot when he lands. Clearly, the official judged him to end the dribble with a foot on the floor, meaning he can't pivot after he lands.
Art. 4. A player who catches the ball while moving or ends a dribble may stop and establish a pivot foot as follows:
a. When both feet are off the playing court and the player lands:
1. Simultaneously on both feet, either may be the pivot foot;
2. On one foot followed by the other, the first foot to touch shall be the pivot foot;
3. On one foot, the player may jump off that foot and simultaneously land on both, in which case neither foot can be the pivot foot.
b. When one foot is on the playing court:
1. That foot shall be the pivot foot when the other foot touches in a step;
2. The player may jump off that foot and simultaneously land on both, in which case neither foot can then be the pivot foot.
