[lit] Fix undefined symbol ArgumentError

Summary:
`ArgumentError` is not defined by the Python standard library.
Executing this line of code would throw a exception, but not the
intended one. It would throw a `NameError` exception, since `ArgumentError`
is undefined.

Use `ValueError` instead, which is defined by the Python standard
library.
