Not really - genetic bottlenecks aren't a feature of intelligent animals, it's a feature of a population that's undergone some kind of very dramatic pressure event like catastrophic loss of habitat or mass illness. Bottlenecks are more likely to be an issue for species with a limited range, population and a slim range of survivable conditions. Intelligence has a way of expanding those ranges by making you more equipped to access otherwise inaccessible resources. Think of elephants navigating between watering holes during droughts, crows using tools to fish out hard to get food, or orcas using sophisticated hunting techniques to get at prey they otherwise could not. Intelligence adds flexibility, and flexibility is especially useful under pressure.
