Thanks for submitting a PR! I left a few questions below
Any chance you could add some test case/s to assert this change will fix the issue?
advanced_filters/forms.py
Outdated

This seems identical to looking up the operator in AdvancedFilterQueryForm.OPERATORS (as on line 124 below). Could you explain what this does differently, and what scenario this will address?

Correct, should be the same. I don't remember the purpose of these lines of mine but I tested it again and it works exactly as your code so we can delete this part. Thanks for double check.

Is this functionally identical to before, or did something change here? Or is the change that isnull operator should return {use key: True}?
From a readability perspective, I think I prefer the previous code

Yes, this is the most important part. Otherwise it returns 'True' value (string) instead of True (boolean), which is incorrect and produces false SQL statement. That's the reason why I iterate only boolean operators ("isnull", "istrue", "isfalse") and not all of the AdvancedFilterQueryForm.OPERATORS.
Except of that. It allows to combine values like following:
isnull: True
isnull: False
istrue: True
istrue: False
isfalse: True
isfalse: False
which can be useful as well.

isnull,istrueandisfalselookups as well as initialising form.
