There are at least two possible answers to the bell inequalities:
1. Nonlocal influences
2. Mutliple outcomes for each measurement

If you choose 2, then you don't need 1. You can have multiple outcomes for
a measurement and realism. You just can't have only one definite real
value, without FTL influences.

It is local, all QM effects under MW propagate at c or slower.  See the
"many worlds FAQ" or the wikipedia table comparing various interpretations.

Locality has a specific definition in physics, that things are only
affected by other things (fields or particles) in direct proximity to each
other. It says nothing about the existence of places we can or can't go to.
