Because the inertial field strength would be almost uniform in the area of Earth, so experiments would not detect a variable G.

And on what basis do you exclude a force that has not been accounted for?
Such as? There have been numerous failed attempts to explain the acceleration (already thoroughly discussed) with known phenomena. If you’re going to consider unknown forces, Jerry’s is as good as any.

Why?
Obviously, the hypothetical inertial field is very slightly stronger on the side closer to the Sun. However, does this not contradict the notion mentioned above, that the field is uniform enough not to affect experiments showing a constant G on Earth? The effect is probably lost in measurement error.
