Gel pens are ballpoints. What do you mean by "ballpoint" here?

I would never choose to use one of those, since they aren't available in 0.5mm. 0.7mm is too thick.
Jetstreams come in a lot of forms, including 0.5mm and 0.38mm I believe.
Not according to Uniball's official website they don't.
https://www.unibrands.co/collections/jetstream?filter.v.opti...
The Jetstream Edge pen uses the same SXR refill size as the 4 colors of refills for the SXE3/MSXE5 multicolor pens; while their website only lists 0.28mm and 0.38mm refills as compatible, the SXR-80-05 refills are also compatible. But I suspect the reason they’re not formally listing 0.5mm support is because the lower-capacity SXR runs out of ink too rapidly when used in single-color 0.5mm, and so that’s why they cap the pen at 0.38mm. Recommend avoiding these as an option.
However!
The SXN-150 and SXN-155 lines deliver normal capacity 0.5mm Jetstream pens; and their SXR-5 refills deliver single-color 0.5mm Jetstream through the SXR-5 refills.

You can search for the often-dehyphenated SXR-5 refill compatibility to see what pens they fit besides the official SXN-150 options (like, for example, the Pentel Energel); MP’s own website isn’t listing the options properly on the refill page — they only list the SXN-155/S and not the SXN-150/C, for example — so some footwork would remain to identify precisely which official model numbers are associated with the 0.5mm refill — e.g. the SXN-150 and SXN-157 bodies sold at JetPens are all 0.7mm/1.0mm but accept any SXR-# refill for # in { 38, 5, 7, 10 }. I suspect any SXN-xxx* body where x >= 150 is compatible with any SXR-y refill, since the discontinued SXN-100 seems not to be and the SXN-189DS seems to be.
Note that I found it rather difficult to locate the SXN-155 body by model number for shipping to the United States; the UPCs for whichever models you want, e.g. 4902778040737, were much more efficient in locating options.
TLDR: Yes, there are official Jetstream 0.5mm pens and refills, in addition to modding any SXR-refillable Jetstream with 0.5mm yourself.
Just checked, their website lists 0.28 mm, 0.38, 0.5, 0.7, and 1.0 mm, with examples of each. [0]
What pens do you find best and what is your use-case?

Except that you forgot to check their website. Jetpens is a reseller.
Uniball only acknowledges 0.5mm for Jetstream pens that include multiple ink tubes in one cylinder.
My use case is that I carry a pen around in my pocket in case I need to write something down. More rarely, I might actually write something down. I don't like writing in thick lines.
The pen I'm currently carrying is one of these: https://img.alicdn.com/imgextra/i3/682114580/O1CN01nP4t8J1jh...

if you're dead set on making sure brand sites match the actual brand offerings then I hope you have the luck to avoid most obscure engineering brands in your life.
it's absolutely the norm in say, hydraulic pumps, that when an offering isn't available on the website you call the company and they say 'Oh yeah, we have those -- theyre not on the site because no one wants one.."

I'm not sure what's your point. Uniball doesn't sell 0.5mm on their website, fine, but jetpens does. Is your point that Jetpens are selling fakes? Seems pretty unlikely.

“Gel pens” are technically ballpoints, true, but when one says “ballpoint” it’s usually taken to refer to an oil based ballpoint like a Bic, whereas gel ink writes quite differently.
