First thing to realize is that the module is designed to go into a breadboard.
That tells you where all the pins are modulo guessing the row spacing, which you can figure in a few seconds with any graphics package by comparing the width to a number of pin spacings. Or take your calipers to your monitor (every PCB designer needs a $12 pair) and do a simple division. And same for the outline.
Next thing to realize is that because it is designed to go in a breaboard, it's not really optimal for a product. For that, you probably want to look at an SOM packaging of the technology, for example the AI7688H. And that does have a footprint drawing in the data sheet (at least for everything except the four afterthought blind pads on the underside).
Finally - I really hope it's universal practice not to invest in designing around an actually avaiable module without buying one to hold in your hand and try out.
