Consider the following:

%%%%
\version "2.22.0"

\relative c'' {
  % Be careful not to stop the ottava too soon.
  \ottava 1 c4 e g f8 d | c2. \ottava 0 r4

  % This encompasses the rest as well but is still a little too short.
  \ottava 1 c4 e g f8 d | c2. r4 \ottava 0
  c8 d b c~ c2

  % This would be nice...
  % \override Staff.OttavaBracket.to-barline = ##t
  % ...but it would appear OttavaBracket is not a
  % line-spanner-interface, where to-barline lives.

  % A manual adjustment is possible:
  \once \offset shorten-pair #'(0 . -1) Staff.OttavaBracket
  \ottava 1 c4 e g f8 d | c2. r4 \ottava 0
  c8 d b c~ c2
  \bar "|."
}
%%%%

Assuming you only have a few of these you need to manage, the manual 
offset might be sufficient to let you move onto other things in your 
score.  But you will need to review these if you make any changes that 
affect the measure length.  An automated approach might be possible, but 
really I think OttavaBracket should support to-barline.  Something to 
submit to the bug mailing list I guess.

Was almost about to hit send, but then I thought... what if you hid the 
OttavaBracket but used a TextSpanner in its place?

%%%%
\relative c'' {
  \once \hide Staff.OttavaBracket
  \ottava 1

  c4 -\tweak to-barline ##t
     -\tweak dash-fraction #0.3
     -\tweak dash-period #1
     -\tweak bound-details.left.text
       \markup \vcenter \bold 8
     -\tweak bound-details.right.stencil
       #(make-line-stencil 0.1 0 0 0 -0.8)
     \startTextSpan
    e g f8 d

  | c2. r4 \ottava 0
  c8\stopTextSpan d b c~ c2
}
%%%%

Hmm... maybe not.  That is a lot of tweaks, and I do not think I matched 
the original OttavaBracket well enough.
