Have you considered deleting the faces (turn off the check
mark) that have the Lisp expressions, saving your theme,
load theme again, and adding the deleted faces by clicking
on ‘Insert Additional Face’ (near the end of the *Custom
Theme* buffer)?

When that is done (starting from ‘emacs -Q’), then Emacs
displays:

     [X] [Tab Bar] face: [sample]
        Tab bar face.
        [X] Foreground: black           [ Choose ]  (sample)
        [X] Background: grey85          [ Choose ]  (sample)
        [X] Inherit:
            [INS] [DEL] Face: [link] (sample) variable-pitch
            [INS]

From there, you could then choose different foreground and
background colors (and the ‘Custom’ menu item is added to
the Emacs menu line, for additional customizations).  Once
you have completed your changes and saved them, you can view
your new TL-theme.el file if you want to study what Emacs
expects in a theme definition.  (Or, you could ignore what
Lisp is required to define your theme and simply use the
Emacs *Custome Theme* interface.)
