Here's the Energiya launch site (a sequence of 360° photos, you can look around). What part of it could rotate, in your opinion? Keep in mind the tower is also missing the massive supports and the cosmonaut escape route, a humongous tube slide that couldn't move anywhere.
You might be thinking of the first R-7 launchpads that had to be rotated to a fixed angle before the launch because the control system from 1950's was unable to compute the roll maneuver in flight, aerodynamics being too complex for it.
Wikipedia makes no mention of that reasoning: https://www.wikiwand.com/en/Roll_program
The roll is part of the gravity turn, every craft does that kind of stuff to 'aim'.
Food for thought, even if they did steal code, what would that have looked like in the 70s and 80s? Printing out reams of paper? Wheeling in a giant hard disk?
The Buran launch pad, by contrast, is able to rotate 360 degrees. They could have just rotated the pad to be correctly aligned before launch. But no, they execute the same complicated, mission-risk-adding roll maneuver verbatim. Exactly like shuttle.
I guarantee you the Buran was running stolen launch sequence code from the Shuttle.
