If she's not used to sharp knives you're not doing her a favour by getting them crazy sharp.
Just get a cheap knife sharpener (not a whetstone) with good reviews and sharpen them a bit once every few weeks, it takes a minute, gets good results, and you can work with her on how sharp they should be.
Most of the time knives that are too sharp are much more dangerous than knives that are too blunt. The people worrying about your knife slipping into your finger have never actually used a knife imo. If it's dull enough to be slipping you'll get a welt before you get cut.

With a sharp knife, you cut through food very easily so you use very little force. You also use techniques that prevent you from getting hurt, such as the claw ( https://www.thekitchn.com/knife-skills-the-claw-75998 ).
But if someone has used a dull knife for most of their life, they may not have cultivated these skills and may hold their knife in an unsafe way and or use a lot of force when cutting.
For someone like that, a sharp knife could be a lot more dangerous, but if they're trained/using it properly, a sharp knife is a lot more safe as it reduces effort and chance of the knife slipping.
My thought process was that anyone who is trained or interested would seek to get them sharpened.
I've been in this position and my partner at the time decided to use a separate set of knives from me, as my sharp knives made her focus on the danger and pulled her out of her zoned out cooking-with-a-glass-of-wine mood.
Fair enough, how she approaches tools isn't my decision.
Respectfully, proper technique is just a matter of searching and reading for 2-3 minutes followed by a bit of practice and repetition to get fast. You can skip the getting fast part if you want. Nobody needs "training" to become proficient with a kitchen knife.
She doesn't care. It's not possible to force someone to be a gear nerd.
She cooks, she enjoys it, she does it with a medium sharp knife that doesn't slip because that's not a real thing, and isn't scaring her because it's just medium sharp.
