I will say that having those multiple functions are a good idea, since it provides functional separation of methods (though not logical).

I posted a slightly better call to tba_send_request which I have tested and works great with errors or without, in all the situations I threw at it (It will throw notices). By the way, is there a better way to link to posts?

make_array is not usually necessary (it has its purposes), because of the method-style member access provided by SimpleXML (e.g. $xml->teams[5]->teamnumber). The only reason I would want to use it is where passing an array would be necessary, like array_map or similar.

I am still interested in the choice to go with a custom format did you ever consider SOAP or XML-RPC (I don't care for them, just want to know if that was a choice)?

Also, I know it looks cool, but PDFs are really inconvenient (I am talking about the API reference), I would focus more attention to developing mediarint stylesheets, and then making PDFs second.
