This could potentially change with Modern Team Sites...but as Santhosh has said you cannot do this with current Groups implementation without having to apply a workaround

It is not possible to share O365 Groups files to the user as you have mentioned. AFAIK, the work around would be to add the user to Azure B2B and share it, if that works. https://azure.microsoft.com/en-in/documentation/articles/active-directory-b2b-collaboration-overview/

Is this correct that currently it is not possible to share individual file to external user, who is not granted access to Group? In this article it is stated that it should be possible:

"The sharing mechanism enabled by guest users accommodates two kinds of interaction with groups. A guest user can be allowed access to a specific file stored in a group document library or they can be granted access to the document library as a whole, in which case the guest is listed among the group membership. In this respect, sharing operates very much like the feature available in SharePoint Online. "

But in fact it is not possible with the error message that external sharing is prohibited if individual file shared for external user, however the same user can be invited to the Group without problems. How it should be by design?

Thank you!

The mechanism followed by Office 365 Groups in general and Office 365 Groups site collection differ by each other. In Office 365 Groups you can able to any member as Guest user which in turn grant the access to the groups document library. But in Groups site collection, you can able to share with external members that are already added in AAD.
