Protecting tub/walls when using self leveler over old tile

We are redoing a small bathroom, attempted to get up existing original 1 inch ceramic tiles, and has been IMPOSSIBLE. We are now planning to just tile over as the floor is solid and quite level, but now we need to level out the area we damaged (about a square foot or so) trying to rip up the old tile, as well as the gaps along the walls where we removed the old wall tiles. Main question, do we have to put down a barrier against the tub ( which will be refinished in the end) or can the self leveler be allowed to run right up against the tub? As far as the walls outside the shower, they are not being retiled (just repaired and painted) , is a barrier needed to prevent self leveler from leaking beneath the wallboards? Any advice?

It's never a good idea to put any kind of new flooring over something old.

I have never seen a tile that could not be simply/easily chiseled off.

Any attempts to shortcut have the likely chance of coming back to haunt you in the future!

Demo hammer and a tile chisel blade will pop the small mosaic tiles off to get you down to the original mudbed. Proper tools for the job are what is called for. If you are trying to manually knock the tiles off, there is your source of frustration. I have done multiple dozens of re-tile jobs by chipping off the existing tile and laying new. The self leveler should be limited to the small gouges you caused during demo of the top tile layer.
