try:

\version "2.14.2"

#(define (forced-dir grob)
  (let* ((x-parent (ly:grob-parent  grob X))
         (elts (ly:grob-object x-parent 'elements))
         (grob-name (lambda (x) (assq-ref (ly:grob-property x 'meta)
'name)))
         (stems (filter (lambda (x) (eq? 'Stem (grob-name x)))
                                (ly:grob-array->list elts)))
         (stem (list-ref stems 0))
         (stem-dir (ly:grob-property stem 'direction)))

    (if (= stem-dir 1)
        (ly:grob-set-property! grob 'direction -1)
        (ly:grob-set-property! grob 'direction 1))))
        

\relative c' { 
        \textLengthOn
        \override  TextScript #'direction = #forced-dir
        a4-\markup { \italic "TextScript"} 
        b'-\markup { \italic "TextScript"}
        c'-\markup { \italic "TextScript"}
        d,,-\markup { \italic "TextScript"}
        e,-\markup { \italic "TextScript"}
        f'-\markup { \italic "TextScript"}
        g'-\markup { \italic "TextScript"}
        a'-\markup { \italic "TextScript"}
        b,,-\markup { \italic "TextScript"}
}

This is of course limited to TextScript. Are you considering other grobs
such as Fingering, StringNumber, StrokeFinger, too?

HTH,
