You can volunteer to help translate here:

https://khanacademy.wufoo.com/forms/khan-academy-translator-application/

And while Haitian Creole is not listed as an option, you can just write it in. I hope you're successful!

Great, thanks.  I've followed and completed that form earlier today.  I got a form response to go ahead and start translating a few videos using the portal --> youtube subtitling tool.  When I get to the subtitling tool, there's no option for Creole: https://www.youtube.com/timedtext_video?v=Q4kxgMH46mY  (of the 187 languages available, Creole is absent)

Thanks for any suggestions.

Wow, they should add that option.  Have you tried filling out a help form here?
