Theoretically, yes, but if a team is going to draft/sign tackles based on their starting QBs handedness, I'd think theyd also have to assess other things like playcalling, play style, etc.
So, as an example: Steve Young was a lefty and the 49ers never had a stud RT to protect him. Those 49ers teams leveraged Youngs legs to run alot of bootlegs. As a lefty, the majority of bootlegs would have Young scrambling towards the left sideline. That actually made the left side of the line significantly more important than the right side of the line despite Young being a lefty.
The Browns, Chiefs, and Packers were 2nd, 3rd, and 6th in bootlegs this season
. Mayfield, Mahomes, and Rodgers are all right handed. It's not a coincidence that they have the 2nd, 5th, and 6th
highest paid RTs in the league.
In other words, theres more to it then just lefty/righty. But, because of the amount of righties in the league, and because of the amount of traditional dropbacks, LT remains the king of the castle for salary.
