English Translation

Wouldn’t a better English translation be “He doesn’t know either of us?”

He doesn’t know both of us.
I checked DeepL and GT and they gave opposite answers.
I think if it was ‘both’, I’d say ‘the both’, but it’s the Japanese meaning that I’d like to understand.
My interpretation is that the 二人とも strongly emphasises the both of us. Like the English equivalent would be something like “He doesn’t know both of us”, with the stress on both. In fact, based on the way it’s phrased, I get the impression that the speaker is implying that he knows only one of us (like only me or only you).
EDIT: To be clear, let me give a bunch more examples:
It is possible that it implies neither, but hmm. That would not be my first instinct.
