There’s a small problem with that theory:
Ion Mihai Pacepa verified that the USSR had conducted Operation Dragon, a KGB disinformation campaign, immediately after the JFK assassination (and he’d know because he was personally involved in planning the operation), and there’s at least one East German spymaster who directed someone to ask Fidel Castro about the JFK assassination when asked about involvement. So unless you mean to tell me that LBJ somehow managed to contact two guys who at that time were loyal to the Eastern Bloc to basically parrot his statements about the Russians being to blame, I think you really need to rework your theory.
Stopping JFK in TX was urgent business such that J. Edgar Hoover helped EL Hunt build a largish FBI/CIA combo outfit with veterans who had lots of chits to call in internationally. Oil barons - who windfalled after JFKS’ hit - chipped in cash and int’l logistics. Imagine what these Texans would have done with bho if they were still around.
If you look at Soviet operatives at that time, the idea that they’d use Oswall is absolutely laughable.
Look at Pacepa’s deposits from the DNC.
Also remember it is NOT LBJ. It is the entire US intel and services. Not to mention his party allies like the DNC.
Look at how many people are out of the loop in US stuff.
The DNC found 17 people in different agencies who would stay they thought the Russians colluded with Trump and we all know what a steaming pile of BS that is!
Besides, if tensions escalated with Russia, how valuable would these former Soviets be to the US government?
If you are really interested in this I’d suggest you check out:

These former US spooks talk to his Soviet handlers anonymously and they completely confirm that Oswell wasn’t even OKed to collect intel, track boats or do ANYTHING with the Soviet Union and didn’t get CLOSE to making the grade.
He tried to be an agent for the Soviet Union, and they wouldn’t touch him with a 10-foot pole.
A larger problem for that theory is Morris Childs. Operation Solo.
Our most valuable spy in the entire Cold War.
Personal friend of the Soviet leadership.
In the Kremlin with his Soviet pals when the news of the assassination hit. They were as shocked as we were, and they were as occupied in trying to guess who had done it as we were. One of the few things that we knew for certain in the days right after the killing was that the Soviets were not involved.
