Why are you reentering all those engravers when you copy them from
\Lyrics anyway?  You can use

\layout { \override Lyrics.LyricText #'font-size = #-1 }

in order to catch all aliases of Lyrics in one fell swoop.  So this
gives

%% Implement an alternate lyric context
myLayout =
\layout {
  \context{
    \Lyrics 
    
    \description "Corresponds to a voice with lyrics.  Handles the
           printing of a single line of lyrics. More lower vertical space
           than default-Lyrics"
        
    \name "AltLyrics"
    \alias Lyrics

    \override LyricText #'font-shape = #'italic
    \override LyricText #'color = #(x11-color 'grey20)
    \override VerticalAxisGroup #'nonstaff-nonstaff-spacing =
           #'((basic-distance . 0)
              (minimum-distance . 5)  ;; <================ more lower space
              (padding . 0.2)
              (stretchability . 0))
        }
        
        \context {
                \Score
                \accepts AltLyrics
        }
        
        \context {
                \StaffGroup
                \accepts AltLyrics
        }
        
        \context {
                \ChoirStaff
                \accepts AltLyrics
        }
        
        \override Lyrics.LyricText #'font-size = #-1
}
