But does that prevent their pesaqim from being binding? In other words,
the vast majority of the observant community accept that a kezayis
is somewhere between the Rambam's estimate and the Chazon Ish's. Does
that mean that regardless of what an archeologist might prove an actual
olive's volume was, lehalakhah a shitah outside that range would be
invalid anyway?

We know the ammah changed in size over the centuries between Sinai
and Churban Bayis Sheini. Is this due to a change in height of people
causing a change in shiur, or is it that pesaqim in shiurim are more
binding than historical reality?
