```python
def create_logic_validator(logic_str: str) -> callable:
    """
    Creates a logic validator function from a string representation of logical operations.

    Args:
        logic_str (str): A string containing logical operations and conditions to be validated.
                         The string should use Python syntax for simplicity, e.g., 'x > 5 or y < 10'.

    Returns:
        callable: A function that takes input arguments and returns a boolean indicating the validity
                  of the logic under those inputs.

    Example usage:
        validator = create_logic_validator('x > 5 and y <= 10')
        print(validator(x=6, y=9))  # Output: True

    Raises:
        ValueError: If the input string cannot be compiled or evaluated.
