But you're always adding one, so you'll never get zero ...

Exactly. We would remove that but we would need to switch between Math.ceil and Math.floor.

Making a function more complex in order to make it simpler to do something the function does not do is not very sensible. :)

What if we just did something like this:

function d(sides, hasZero = false) {
  return hasZero ? Math.ceil(Math.random() * sides) : Math.floor(Math.random() * sides);
}

If you want to generate integers in a range, you might as well just do that.

But the first thing to check are the requirements for this use case.

I believe that none of these dice include zero. :)
