Here I have results from Intersection Line Plane (green dot) and Ray Cast (red dot). White dots represent a Line.

I don't understand why does ray casting tell me there is no hit?

The Ray Cast BVHTree node takes a Start and a Direction, not an End. To compute the ray direction vector from the line, you can subtract the start and end of the line to get the direction.
