You'll find that this only happens for guitar tablature, not bass guitar
tablature.  Whether a brace is placed or not depends on the height of
the system/group.

Try

\version "2.20.0"
music = { c''1 }

\score { 
          <<
 \new ChoirStaff \with { \override SystemStartBracket.collapse-height = 8 } <<
                    \new TabStaff = "Part 1"  << 
                                 \music
                        >> 
                    \new Staff
                        << 
                           \new Voice { 
                                        \music
                                      } 
                        >> 
                 >>
          >>
       }

instead.  Yes, this is somewhat insane.
