Here's a stencil callback reading the vertical start
and end positions of the arpeggio and printing a bracket
accordingly:

\version "2.22.1"

arpeggioBrace =
\tweak stencil
  #(lambda (grob)
     (let* ((positions (ly:grob-property grob 'positions))
            (layout (ly:grob-layout grob))
            (scale (ly:output-def-lookup layout 'output-scale))
            (factor (/ scale (ly:pt 1)))
            (len (* factor (+ 0.5 (interval-length positions))))
            (brace-markup (make-left-brace-markup len))
            (brace-stencil (grob-interpret-markup grob brace-markup)))
       (ly:stencil-translate-axis brace-stencil
                                  (interval-center positions)
                                  Y)))
\arpeggio

\relative {
  \clef bass
  <e g b g'>\arpeggioBrace
}


Best,
