apple tv thunderbolt port for older Sony TVs

You should have HDMI inputs and then you can just use an HDMI lead between the ATV and the television.

For Sony TV model #KDS-50A2020 do I need a Thunderbolt port to display Apple TV?

No. No idea where that question came from since AppleTV does not use or have any thunderbolt ports. It only uses standard HDMI.
