Well, Roll20 does, though that may be a bit more than what you are looking for. I’m guessing you aren’t as worried about the “random seed” to make sure the dice are as random as possible.
There is an App that someone has made in the community which can roll dice:
As far as the Character Sheet, I typically use Acrobat DC for PDFs but there are free options out there. You can also just create one simply in any word processor or spreadsheet type program.
Do you already have the “simpler” words picked out for each Attribute. I know there are some in the community that could probably whip you up a sheet (myself included, though I am traveling right now so might have to wait a week until I get back if no one else does).
