ELI5: If pre-election polling is mostly done by phone interviews via landline, and the number of landlines is declining among most demographic groups, why are they still fairly accurate?

It is not accurate that "... poling is mostly done by phone interviews via landline". Actual polling companies call cellphones and have non-phone ways of reaching people. "Polls" limited to landlines are badly disguised political activism.
