```python
def create_logic_validator(logic_str: str) -> callable:
    """
    Create a logic validator that evaluates if the given logical expression is valid.

    Args:
        logic_str (str): A string representing a logical expression. The expression must be in a simple,
                         boolean context where 'x' and 'y' are variables, and operations are limited to
                         'and', 'or', 'not', '==', '!='. E.g., "x and not y" or "(x or y) == (not x)".

    Returns:
        callable: A function that takes two boolean arguments (x, y) and returns True if the logical expression
                  evaluates to true for those values, otherwise False.
    
    Raises:
        ValueError: If the input string is not a valid logical expression.
    
    Example usage:
        validator = create_logic_validator("(x or y) == (not x)")
        print(validator(True, False))  # Should print True as the expression evaluates to true
