Wouldn't that have been happening before the boiler turned off?

The boiler would probably cycle off on its own stat in the circumstance.

Just one of those cases of not being able to win em all!

Thought it wasn't recommended to have TRVs on every rad?

Its isn't generally - although you do find some systems that have no
main stat and have all TRVs.

(Some systems have a bypass to ensure there is always an available path
for flow, and some modern boilers include an internal one (as does my
Vaillant for example)).

I have none in the living room and that's where the main temperature
sensor is. Every other rad has a TRV.

Yup, similar arrangement here - although I have a second zone upstairs
where all the rads have TRVs, you get enough heat leakage into the
landing (where the zone stat is) from downstairs to satisfy that stat
anyway.
