Q: Is there a way to construct a vector line(s) map connecting selected points?

A: You can use v.in.lines for that. The input can be generated with v.out.ascii.

Spearfish example:

 v.out.ascii archsites fs=, where="cat=1 or cat= 3"
 593493,4914730,1
 589860,4922000,3

 # so:
 v.out.ascii archsites fs=, where="cat=1 or cat= 3" | cut -d',' -f1,2 | v.in.lines in=- out=myline fs=,
 v.category in=myline out=line_with_cat option=add
