ODbL (which is the license for the data) doesn't require any particular
license for maps produced from ODbL data. (And in the U.S. data isn't
copyrightable anyway.) There is a copyright on the style and presentation
of the tiles which is separate from any copyright on the data. This
copyright belongs to whoever created the styles for the tiles (or their
employer). Unless whoever that is explicitly puts it under a license, the
style of the tiles is fully copyrighted (in the U.S. at least).

I feel like there's an argument to be made that
the images are a derived
work from the data itself, so it may be best to just stick with OSM's
license rather than run into any possible issues. (Also, of course, I am
biased and prefer copyleft licenses since they support free information.)

to link to a big explanation from each tile rendering :)
