Hm, possibly? I mean, I luckily don't have diabetes and know the Libre 2 only second-hand (my Dad uses it to monitor his non-T1d). So I am not too familiar with the details, hence first of all thanks for the clarification of what that device can or much rather can not do.

However, I was under the impression that the GP [emj] was "only" considering good monitoring to improve their decision about insulin application. Not a closed loop system. But yeah, if they meant a closed loop and if the Dexcom is the cheapest option here, then the 300 US$/month is actually cheaper than the 380 US$/month you outlined.
