More of a general answer than for CS, but for bachlors or masters (some are IT-related, maybe not as cool as you are looking for): check out WGU (it has been discussed on HN before, or https://en.wikipedia.org/wiki/WGU or https://www.wgu.edu/ .
Edit: the reason I mention WGU is that it is accredited (lots, looks like), well-regarded AFAIK, you get credit for what you already know (test out), and take as many classes as you want in a semester for a flat fee (or some such), so you can do it for less $ if you are experienced or have learned material previously. And remote-friendly, I believe.
And in the never-give-up category, 89-year-old becomes a physicist:
Yeah, OP is basically the perfect candidate for WGU. With transfer credits and work knowledge they could probably get a bachelors in a year and go on to OMSCS.
