hack to auto-define variables?

In the example you use to justify this travesty, you can do what you
describe with __getattr__, if your heart's set on it.

class Base_travesty:

    def __getattr__(self, attr):

        setattr(self, attr, None)
        return None

t = Base_travesty()

assert t.x == None
t.x = 1
assert t.x == 1

You could extend this with code that stored a traceback each time the
__getattr__ method was invoked, too.
