She's clearly too young to have her own practice. Whatever firm she works for placed her on his case. Her intelligence cannot be defined by the client she represents. She's smart enough to pass the bar. I'd wager she's also smart enough not to hand her personal laptop to some neckbeard to set up for her. It's highly questionable at this point whether Trump can even get a firm big enough to have in house IT to work for him.

If you care for a personal example, the company I work for has IT which give us work phones. The IT department set the phones up themselves. Because of the way the phone has been set up, there's incredibly little that can go tits up and there's a lot of security built in (no admin, enforced long passwords, probably more that I'm forgetting).

I'm more than capable of setting up my phone and having it be secure myself without IT doing it. Maybe she can too. Is it a usual thing for IT to thing up in a business setting, (unless you're a programmer) probably.
