Well, Judaism as a whole tends to be more than a little reticent about conversion; assuming the aliens/AI weren’t part of the original covenant (that would be a cool plot twist, though), you’d probably see more resistance among orthodox groups, but Reform groups wouldn’t be actively encouraging it, either. Even for Reconstructionists, a large part of the underlying ideas revolve around a shared history. You can read more in-depth about the conversion process/differences in Christian vs Jewish attitudes towards conversion over yonder.
On a larger scale, humans being humans I’d expect widespread discrimination against non-humans (I mean, if some people care so much about variations in skin’s melanin content, imagine a whole different species). As a result of that, it might be harder for a Dalek to convert than your average gentile.
