I think the title organization is not a legal term and therefore can be used by anyone for anything. To be official, you either just have to register your “organization”, just announce your existence, or not even this, depending on the used meaning of " official".
If this is the official website of that organization, there is no way mentioned to become a member of the organization. There is also no information how to get your own software certified, nor what it means to be certified.
This is just a marketing stunt.
To quote thir website (which doesn’t seem to have any subpages btw)
We are developing top-class Artificial Intelligence Board Games for iOS/Android smartphones, Windows PC, Nintendo Switch™ and Sony PlayStation®4, and have great experience in AI-based board games.
Sounds just like a (software) company.
