Has an Olympic Basketball (Men) game ever ended 34-29?
Exactly once. On August 7, 1936, Estonia beat France 34-29, and no Olympic Basketball (Men) game before or since has ended that way. When it happened it was a scorigami, the first 34-29 in league history.
That makes 34-29 the 126th most common final score out of 698 that have ever occurred in Olympic Basketball (Men). One point away, 35-29 has happened never and 34-30 has happened never.
