Neither, lithium nitride is ionic. It has a very unusual lattice (see link) and is a "fast ion conductor" - meaning that it does something really unusual - the ions are free to move ( a bit) and it conducts electricity.

Li2S is a polar covalent compound because the electronegitvity of Li is 1.00 and of S is 2.5. Thus the difference is 1.5 and that makes it polar covalent.
Polar substances dissolve other polar substances, and nonpolar substances dissolve other nonpolar substances. A polar substance cannot dissolve a polar substance and a nonpolar substance cannot dissolve a polar substance.
The shape is trigonal bipyramidal and all the atoms on the outside are the same so the charges cancel eachother. Nonpolar
