any way to make mule accounts quickly?

seems like gaia's blocked every single temp mail domain, which would have been my go-to. Google accounts require SMS verification, and I don't have 7 different phones lying around. And it's just an irritatingly long signup process besides that.

are there any programs that can automatically create multiple email accounts in a relatively short amount of time?

Last time I checked you don't need SMS verification for google accounts (unless they've changed that in the last month or so). If you put in an alt email address you don't need SMS and you can put the alt email as one of the disposable ones.

My "go to" disposable is @grr.la

Use Yahoo if you want to make a bunch of emails. To my knowledge, you can use the same phone number for Yahoo accounts.
