Can you create an overload that says if other: _str, the result is Series[str] ?

Plesae move the new test to tests\series\arithmetic\test_add.py and make use of left_str.
Probably we need to make the same valid tests in tests\series\arithmetic\str\test_add.py (excluding the TYPE_CHECKING_INVALID_USAGE ones) work for Series[Any].
For consistency, we probably also need to make Index[Any] + str etc. work
