So, should all Yaks (excluding the Yak-3 VK107 and Yak-9U) and LaGGs as well as the La-5 & La-5F suffer from neg G cutouts as we see them on the early Spitfires now?

True for very early 1939/1940 aircraft such as the very first Yak 1's as these were equipped with the M-105P.
From the M-105PA (1940/1941) onwards a new carburetor (without a float chamber) was used avoiding the negative G problem.
