Sadly the options are very limited it seems. There are a handful of state schools that either offer them to people who have some existing college credi (not if you dont have any prior education) or offer made up bullshit sounding degrees for "continuing professionals". There are also for profit school and school that seem to not be outright scams, but might not be high quality (e.g. WGU)
So if you just want to check a box for grad school or to bypass ATS filtering, etc. you have a few options, otherwise you might be out of luck

BS degrees in the UK are a little different than in the US, 3 years is standard because a lot of what would be first year coursework in the US is covered and credited by their GCSE/GCE exams(somewhat similar to to how you can test out of lots of first year credits in the US with AP tests).
In any case I've never seen anyone with a UK degree have any difficulty having it being equated to a US degree for hiring purposes, and that online CS degree from University of London specifically requires 30 hours of college credit from US students so it still comes to 4 years in the end.
Athabasca University offers a 4 year, Canadian distance Computing and Information Sciences Bachelors. It's affordable, the whole thing is under $40K CAD ~= $31USD. Just a suggestion for the non-Canadian Hacker News set.
