I think there might be a more beautiful solutions to your whole situation, but
I’m too tired to figure it out right now, so:
You can change the arpeggio’s Y-extent to prevent it from pushing away the
other staff.
%%%
\version "2.22.2"
rightHand = {
e'2
}
leftHand = \relative {
\clef bass
<<
{
\slashedGrace {
e8
\tweak positions #'(-4.5 . 7)
\tweak extra-spacing-width #'(-1 . 0)
\tweak X-offset -1
\tweak Y-extent #'(-4.5 . 2)
\arpeggio
}
<e gis>2
}
\\
{
<cis, gis'>2
}
>>
}
\new PianoStaff <<
\new Staff \rightHand
\new Staff \leftHand
>>
