It's the other way around. Governments & government employees have various forms of legal immunity. FAA employees are immune from most lawsuits (including claims of negligence) arising within the scope of their employment.
Privatized ATCs are more exposed to liability. In fact one of the reasons to privatize is to make ANSPs more accountable. When AF358 overshot the runway at Pearson airport and ended up in a ditch, Air France promptly sued NAV CANADA.

Electronic charts have been available for several years now through NAV CANADA's partnership with ForeFlight (and possibly others).
