I was thinking about these Russian (not Soviet) spies that were recently arrested.
If they ever make it back to Russia, they will be lauded by the State with pensions and sinecures. But what about the kids? They are US citizens and not guilty of anything.
If a Russian charity nobody ever heard of suddenly began to pay all the kids involved a nice stipend, would that violate US law? I would suppose such an act would motivate future (or as yet undiscovered) spies.
if all else fails, the kids will register as foreign agents :-). Or, maybe they will just go back to Russia and live with relatives.
Note that it is not illegal for citizens or non-citizens to be in the employ or otherwise financially supported by a foreign government. You just have to register with FBI if you happen to be engaged in certain activities specified by the law.
I would suppose the kids involved would never want for anything as long as Mom and Pop are in jail.
and just who is going to care for them? The Russian Gov’t? kind of pokes a hole in the whole deniability thing doesn’t it? Not a good idea until all the appeals are done. The US Gov’t probably. Perhaps the state. I assume the kids are in foster care.
Perhaps these folks will get off with time served and allowed to resume their original lives. Wherever those might be. 
The New York Times explained the other day that being as the crime did not involve any sort of abuse, the parents still decide what is best for the kids. Neighbors or friends most likely have the kids.
If the Russians wanted to fund the kids, I am sure they would find a quiet way to do it.
I could tell you, but then I’d have to kill you.
If you did that, would you set up a charity to take care of the kids?
OF course the people who are admitting to stuff in court, rather than doing hard time for the Motherland might be talking themselves out of any sort of consideration from Moscow.
