Looks far too complex.  Just take the original and insert #{ \markup
\normal-text ... #} instead of "...".  Let's see:

Oh, we have to deal with "xxx" being used as part of quoted constants
too, but that's fairly manageable.

%\version "2.16.0"
\version "2.17.26"

music = \relative f {
    \clef bass
        c4 c c c |
%\repeat volta 2 {
\set Score.repeatCommands = #'(start-repeat)
        g2_\markup { \bold \italic "ad lib. vamp" }
        g2 |
% alternatives:
\set Score.repeatCommands = #`((volta ,#{ \markup \normal-text "repeat ad lib." 
#}))
        c2 c c r2
\set Score.repeatCommands = #`((volta #f) (volta ,#{ \markup \normal-text "last 
time" #}) end-repeat)
        d2 d
\set Score.repeatCommands = #'((volta #f))
        f2 f f r |
}

\score {
        \music
}
