No — Trent Olsen's handedness is not currently confirmed by reliable public sources.
James Trent Olsen, often known as Trent Olsen, is an American actor and brother to actresses Mary-Kate, Ashley, and Elizabeth Olsen. He has primarily worked behind the scenes in various production roles and has had some minor acting appearances.
Growing up in a family heavily involved in the entertainment industry, Trent has maintained a relatively private life compared to his celebrity sisters. He attended the New York Film Academy, pursuing his interests in filmmaking and writing.
While not as widely recognized as his siblings, Trent has been credited for his work in projects such as 'Oldboy' (2013) and 'Gangs of New York' (2002), though often in uncredited or minor roles, or behind-the-scenes capacities.
His career has shown a focus on creative endeavors, including screenwriting and directing, rather than being a prominent public figure. He occasionally appears at family events but largely stays out of the mainstream media spotlight.
