Poor accuracy is probably due to slower rate of fire compared to other heavy guns in game (which means it would take longer to bracket enemy) and historical reasons - Littorio class had some rather face-palmingly bad episodes, probably because of poor quality ammo with inconsistent parameters. With good ammo in test conditions those guns were actually among the most accurate (flat trajectory and stuff) - just IRL they underperformed badly.

Radar doesn't really even come into picture, as back then guns were aimed with optical rangefinders and good, old, manual correction (assisted with planes or just with Standard Eyeball mark 1).
