Why did City of Nolensville Police Department encrypt their radio?

The standard justification nationwide is officer safety and operational security, regardless of whether a documented local incident ever required it. The tradeoff that follows is consistent too: public oversight drops, and reporters lose the ability to track police department response as it happens.

Can Williamson County reverse the encryption decision?

Yes — nothing about the underlying radio technology forces this. It's a decision Williamson County officials made and can revisit, and other communities have pushed departments back toward open channels through sustained council pressure and coalition-building.

What can I do about City of Nolensville Police Department encryption?

Three things carry weight, in this order: a public-records request for City of Nolensville Police Department's encryption policy and radio recordings, a turn at the microphone during Williamson County budget discussions, and finding the other people locally already asking the same question. Individually these are easy to deflect; together they are not.
