A feature request about dotted or dashed LyricExtenders needs to be
send to the bug-list.
Although this feature was requested before, it never reached the buglist.

Once 2.19.60 is released you could do something at the lines of:

\version "2.19.60"

dottedExtender = {
  \override LyricExtender.style = #'dashed-line
  \override LyricExtender.thickness = 2
  \override LyricExtender.dash-fraction = 0
  \override LyricExtender.stencil =
    #(lambda (grob)
      (let* ((stil (ly:lyric-extender::print grob))
             (x-ext (ly:stencil-extent stil X)))
         (make-connected-line
           (list
             (cons (car x-ext) 0)
             (cons (cdr x-ext) 0))
           grob)))
}

<<
\new Staff { c'2( d' e' f') g' }
\new Lyrics \lyricsto "" { \dottedExtender foo __ bar }
>>

HTH,
