So, who was going to tell him? SWORD? With that idiot at the lead? No.
Monica Rambeau or Agent Woo? They don't know Strange.
Beyond that, nobody knew it was happening.
I would argue the head of Sword at least for most of the show is not stupid, he's just evil. He's much less of an imbecile than Monica is, who:
- Who faced with some mystery field surrounding a disappeared town that has clearly mind whammied local police, decides the best idea is to the touch it....then try to move through it, instead of calling for backup.
- Is on record saying that Wanda's manipulation was "agonizing torture" but still defends Wanda to the rest of the organization....based on some....gut feeling?
- Finds out that she went through a reality changing barrier, then gets a note from the medic that her "medical signs aren't even showing up"....and just decides to blow it off instead of taking it for the grievously serious news that it should be. Actually that should have been illegal, Monica should have been medically detained at that point...but I digress.
- Then goes through the same barrier....again! Its only by the power of plot she got super powers and not extreme cancer that killed her in a few days.
In contrast, the head of Sword is on point for most of it. He sees Wanda for exactly what she is....an enemy of extraordinary power who has taken an entire town hostage, and when confronted, shows no remorse and no desire to stop her actions. He uses that drone to take the one shot he's got to take out the terrorist (which Wanda absolutely is at that point)....sure it doesn't work, but against Wanda I mean what would? Sure the guy had an evil agenda, and turned into a mustache twirling villain by the end (which was so stupid....sigh), but honestly for a lot of the show he was right.
Back to contacting the Avengers, Agent Woo knows Ant-man, Darcy knows Dr Selwick that have worked with Avengers and likely have some kind of contact number for at least a few of them. Falcon and War Machine are well known military assets that would definitely have ways to get in touch with them. Or Pepper Potts, surely she has some Avenger contacts in that massive rolodex of hers, and again a federal agency would absolutely have means of getting in contact with her.
So would it require some telephone games sure....and you put one of your hardworking federal agents on that while people continue the investigation....but that absolutely happens.....because when you are dealing with freakin reality changing magic....yes you are going to try and find any expert on the planet....or heck beyond the planet....you can.
But....again in my headcannon, I assume they do just that. There is a poor federal agent in their camp who makes dozens and dozens of calls trying to get a hold of an avenger....and for XYZ reason they just can't....and so the plot moves on.
