usually centering markups can be done like this:

[...]
\markup \fill-line {
      \override #'(line-width . 60)
      \column
      \table-of-contents
}
[...]

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



Alternatively, how about:

\version "2.22.1"

\paper {
  tocItemMarkup = \markup \fill-line { \override #'(line-width . 60) 
\tocItemWithDotsMarkup }
}

\markuplist \table-of-contents

#(for-each (lambda (i) #{ \tocItem #(format #f "Piece ~a" i) #})
           (iota 100))

{ c' }
