On the node stream of the curve, add a Point Wrangle, and on the second input of the Point Wrangle node plug the letter geometry.

Put the following VEX code in the Point Wrangle:

vector pos = minpos(1, @P);

v@N = normalize(pos - @P);

This should orient your points normals toward the geometry. You can then instance your tubes on these points (nevertheless, be careful of the orientation of the tube beforehand...)
