Her hands don't shake so much yet that she triggers Shake To Undo, it's more about things like the screen detecting the start of a swipe when she wants to do a long press. I also think Touch ID can be a bit confused by slightly shaky fingers.
I'd really value guidance from people who've gone through the same process, either with relatives or themselves, whether through age or conditions like Parkinsons, so I can at least have a starting point to work from.
She recently bought one of the new iPhone SEs, but I'm wondering if it wouldn't be better to get an XR with FaceID to avoid issues with TouchID.
One particularly troublesome problem with the Phone app is that touching just about anything accidentally initiates a call. That was hell for my mom and I'll bet your mom has it worse.
One thing I always wish the Phone app had was a "confirm" dialog when dialing a number (like what you get when you tap on a phone number external to the Phone app)
on a similar note, I know Tesla's UI is probably tested at a desk where everything is visible and stable, but in a moving car doing things like scrolling through a list of music and selecting is almost impossible.
Then on iPad Mini, use max zoomed UI.
A significant degree of shakiness perceived by the device comes from tentative behaviors while she is trying not to miss small targets. With larger targets, she can point and touch with more confidence due to larger margin for error.
I'd suggest give Voice Control a try, it can do swipes, clicks, etc:

Unless she’s a very savvy 89 year old you’d probably need to set up the different workflows for her but IIRC it will suggest some of your most frequent actions when you launch the app. They also have a gallery of actions you can browse and might find something helpful.
Edit: It looks like they even have an “accessibility” section in the gallery.

I have an essential tremor (I'm 34, my mum has the same tremor, and I've had it since I was a child), and it was able to be stopped almost completely with Propranolol, a beta-blocker. I'm not a medical professional, so I'm not sure whether that's a good suggestion for your mother though, so seek professional assistance first.
Of course it wouldn't solve the problem, as you still have the other hand that has to touch buttons. I ask because I recall seeing a "smart" spoon: https://www.youtube.com/watch?v=WiVQcgmIi08

This condition is called Essential Tremors, and it is one of the impacts of increased mTOR and IGF-1 levels that so many of us have from eating too much meat. According to Dr. Oliverirea, as an example, in her presentation she showed that eating 1.5 ounces of chicken per day, increases your chances of getting Essential Tremors by x21!! Wow. Eating meat and diary in excess has consequences and there's a lot of research to back that up.
Unfortunately, it maybe to late for your mother. But, this is for all the other mothers and fathers out there.
The solution is to stop using iPhones and use something that interfaces with her better.
Big physical buttons is a good start.
