Not sure her age - but sounds like minimally a soph on a Varsity HS program so 18U eligible.
The short answer at this age: No; this is on her now. She has to figure this out herself; if she even thinks it is a problem. If you stop trying to micromanage how she plays you (and her) will enjoy this more. Having parents chirp on about striking out is as likley to annoy her and stress her more and make it worse; not better. If she asks for help, great; now you can talk through approach because she asked.
My DD expects to strike out on occasion because she also expects that she is going to crank a couple over or to the fence to make up for it; and as long as the pitcher is quality she can live with getting fooled by a good pitch. A strike out doesn't bother her at all - she just figures she will get the pitcher next time. Travel pitchers/travel hitters - sometimes you get them, sometimes they get you.
Second - if you can intentionally 'foul off 2 strike pitches' then you might as well intentionally square the ball up and hit it fair. Fouling off 2 strike pitches are just you trying to hit what you think is a strike. That is just hitting. Fouling it off just means you didn't get the contact you wanted 99% of the time.
Love these:

so much of this is about attitude and expectations. Expect to get a hit...but if you don't have the right attitude about it..... Reggie jackson is MLB all time strike out leader....yet we don't remember him for that. We remember him for being clutch and 'Mr. October'. He knew that for every 10 K's he hit a home run. His attitude if he struck out....I'm one more strikeout closer to another home run. Perspective and Attitude towards the situation...
