Will the `smartctl -o on /dev/sdx` (for > each sdx), fix the nonzero
Reallocated_Event_Count issue on RAID arrays in a non-desctructive

No. Nor for non-RAID either. It doesn't "fix" Reallocated_Event_Count
-- rather, its purpose is to make Reallocated_Event_Count go up faster,
in that as soon as a sector starts to go bad it will be reallocated if
readable, and the sooner the more likely it is possible. A non-zero
Reallocated_Event_Count is not a problem. Whatever says it is a
problem is the real problem. Fix that instead.
Non-zero Current_Pending_Sector is a problem, but RAID should be fixing
that already. I don't know, but I think that enabling Automatic
Offline Testing should cause any uncorrectable sectors to be noticed
and fixed sooner by RAID.
Do you have to use the /dev/sdx devices or the /dev/md devices?

Automatic Offline Testing must be enabled on an actual ATA hard disk,
so no fake disk such as dm or md. See `man smartctl`.
With the changes, I was shocked to see the error message when I tried a
live DVD on my laptop. It would be worthwhile to have a tool for
testing and possibly fixing the problem in a non-destructive way for
most users. I guess it is time for an RFE search.
