*Following* a link with a line number is no problem: org does that out
of the box with a link like

[[file:foo.txt::NNN][desc]]

That is actually documented: (info "(org) External links")

The problem is to make sure org-store-link will actually store the line
number (along with everything else) so that then org-insert-link can
insert the link in the proper format. I don't think there is a function
to do that out of the box for line numbers, but you can easily (for some
value of "easily") write your own. Look in

(info "(org)Adding hyperlink types")

for some hints. Briefly, you write a function that checks whether it
wants to deal with the link or not, and you add it to
org-store-link-functions. I don't have the time to try it out right now,
but I believe this should work for what you want.
