    A function that generates a logic validator for simple conditional statements.
    
    This function creates a class `LogicValidator` which can be used to validate if
    given input conditions hold true according to predefined rules.
    
    The class is designed to handle logical operations such as AND, OR, and NOT with
    a limited reasoning sophistication, focusing on simplicity and clarity.

    Returns:
        LogicValidator: An instance of the `LogicValidator` class.
