As the other anon said, Olka knows they're for cover, which she must've been told by Shopkeeper. She wouldn't have just assumed considering she's underworld herself and she had a real family. McMahon had a real wife too.
McMahon also tells her that Loid would be informed that she had a work transfer if she were to be killed or maimed. For him and Shopkeeper to think that would be acceptable to him, they must think the relationship is purely business.
>Like he is not aware of the whole fake marriage for Eden deal they have going on
This has never been specifically addressed, but it doesn't seem like Yor keeps anything from Shopkeeper. It's probably only a matter of time until she admits to him she's in love with Loid. I doubt he'll be happy about that.
