Repairing textured walls
You can ask anything you want from the seller.  Replace the roof, add a garage, repaint, remove shrubbery, fix a sewer line, replace the fireplace, etc.

Typically the seller will either reject any involvement in such projects (considering them excessive or unnecessary for adequate living conditions), or agree to a lower price to offset your cost of doing it yourself (or by a contractor).

Around here (Oregon), wall hanging holes are considered part of the normal wear and tear of a home.  Usually, it isn't much work to spackle the holes, sand, and repaint to get a passably virgin-looking surface.

If there is a serious degradation of the wall surface&mdash;beyond normal wear (for example 10 years of missing a dartboard)&mdash; you could ask for sheetrock replacement but that would only seem sensible if the wall has widespread major damage evident by its very structure being weakened.
