Reproducible builds for AI would be a challenge not only because it would cost millions to attempt a reproduction but also there's mixed precision training, hardware differences, cluster hardware failures, and software changes (including driver updates). Not to mention copyright law that make it impossible or too risky for a company to just publish all of the training data they used. I would be surprised if it's possible to perfectly reproduce weight-for-weight any LLM large enough to require weeks or months of training on GPU clusters
