Rarely do they get moved, but let's take a look.
These are the teams that could use Strome, plus the young top 4 lhd they have:
Boston: Urho Vaakanainen?
New Jersery: Ty Smith?
Detroit: Dennis Cholowski? Jared McIsaac?
Montreal: Alexander Romanov?
Ottawa: Thomas Chabot (untouchable), Erik Brannstrom? Jonny Tychonick?
Dallas: Miro Heiskanen (untouchable), Thomas Harley?
Minnesota: none
Nashville: none
Anaheim: Jacob Larsson? Brendan Guhle? Josh Mahura?
Arizona: well...they probably don't want Strome
Los Angeles: Tobias Bjornfot?
Vegas: Shea Theodore (won't be available), Nicolas Hague?
Columbus: Zach Werenski (untouchable)
San Jose: Artemi Knyazev?
So basically the only proven top 4 D options here are untouchable. You'd have to go after a prospect that you believe is a sure thing, but also one that the team you're trading with could do without.
Ty Smith, Erik Brannstrom, and Alexander Romanov probably have the highest upside. I highly doubt New Jersey would trade Smith for Strome, since they will want to bank on Hischier and Hughes being their centers. Montreal has Suzuki and Kotkaniemi.
So Ottawa's Erik Brannstrom is the only option I could see.
EDIT: I forgot about Calgary. Strome for Noah Hanifin could be another option.
