Choose the largest component of plane normal and make projection onto corresponding plane OXY, OXZ or OYZ (in general we can use any non-zero component)

Say Z-component is the largest, so make projection onto OXY plane. This projection is very simple - just use X and Y components. You have rather simple 2d problem now. (Example for line segments intersection).
