A few thoughts.
First, if the speed is below Va and therefore lift is AOA-limited, then you're right and strictly speaking, the boards will further limit lift and therefore reduce the pullout-radius-shrinking normal force. However, without a AOA meter and a confident pilot willing to pull all the way to the limit, it is extremely unlikely that the full AOA lift potential will be used to begin with. In that case, the speed brakes' effect on reducing pullout-radius-growing airspeed, will be overall beneficial.
Second, if the speed is above Va and therefore lift is G-limited, then the speedbrakes will have no negative effect and only positive. Third, with the nose significantly below the horizon, if airspeed is below Va, it will be above it very soon anyway.
