Most forks are re-build-able, it comes down to if you can get spares, and even if you can, it is cost effective vs a replacement fork. Going that you have a RS Tora, spares should be available, but would look at service cost vs replacement, especially if there is any stanchion wear / corrosion.
For the axle size, it's not about it being strong for dropoffs, more that a thru axle (Maxle) hub will stiffen up the front end, meaning the tracking of the fork is better, i.e. it goes where you point it.
