Ofcourse you should use Staff.OttavaBracket, but in `octU_single'
OttavaBracket.stencil is set to ly:line-spanner::print, which doesn't
support 'shorten-pair, as far as I know.

You would need to do:

"testing2" = {
  \octU_single
  \once \override Staff.OttavaBracket.bound-details.left.X = #-10
  \once \override Staff.OttavaBracket.bound-details.right.X = #10
  c''''1
}

\score { \"testing2" }

That's the disadvantage of using ly:line-spanner::print as stencil for
OttavaBracket.

P.S.
There were some typos in your post, making it hard for people helping you

error: syntax error, unexpected '''
  \once \override Staff.OttavaBracket.shorten-pair = #'(-10 . -10)
\octU_single c''’

             '1

error: EOF found inside string
\score { \"
           testing2” }
