There are a lot of very intelligent Russians. Some of the liberal ones are leaving, but I imagine there are still a large number of intelligent Russians who are willing to work for their country's defense industry.

And even if they don't have the capability of fabricating chips with the current world record line widths, I'm sure they can develop and fabricate computer chips that are acceptable for putting together the electronics for a fighter jet.

Being part of the BRICs, they can get all the raw materials they need for building airframes, etc.

And their spy network is still operational and capable of getting designs from the US, UK, and China if/when necessary.

the most advanced chips are for consumer devices, advanced graphics, etc... A lot of US military hardware has specs for chips from the 1990s and earlier.

“I’m sure they can develop and fabricate computer chips that are acceptable for putting together the electronics for a fighter jet”

Well, history would say that speculation is probably far too optimistic. Russia can’t even retrofit their existing air force with modern targeting and radar systems, so why should we assume they would be able to do it for a brand new aircraft that will need even more advanced systems?
