Look at rule 10-6-11 where it states that player shall not commit illegal contact including but not limited to guarding as in 4-23, rebounding as in 4-37, screening as in 4-40 and verticality as in 4-45.
Basically you do not need LGP just to call a player control foul. It would be nice, but not absolutely necessary.
Peace
