This will work, unless the TOC will exceed one page.

Probably:

#(define-markup-list-command (tst layout props args)(markup-list?)
  #:properties ((line-width))
  (let* ((layout-lw (ly:output-def-lookup layout 'line-width))
         (diff-lw (- layout-lw line-width)))
  (map
    (lambda (x) (ly:stencil-translate-axis x (/ diff-lw 2) X))
    (interpret-markup-list layout props args))))

\markuplist
  \override-lines #'(line-width . 60)
  \tst \table-of-contents
