Their relationship could have a big impact on the medical aspect in the Naruto world. Sakura is a great medical ninja. If she was friends with Itachi from childhood, she might have been inspired to develop new medical techniques to help Itachi with his eye problems or any other ailments he might have had. This could then spread throughout the Leaf Village and improve the overall medical capabilities of the village. And in the grand scheme of things, the Leaf Village being stronger in the medical field could change how battles are fought and how alliances are formed in the Naruto storyline.
Well, their friendship could potentially change Sasuke's path. Since Sakura is friends with Itachi, she might be able to communicate better with Sasuke about his brother. For example, she could tell Sasuke about the good side of Itachi that he never knew, which could make Sasuke less vengeful and more focused on rebuilding his clan. This would be a huge shift from the original storyline where Sasuke is mainly driven by revenge against Itachi.
If Itachi and Sakura were childhood friends, it could also impact the Akatsuki. Itachi might have second thoughts about some of the Akatsuki's actions because of his friendship with Sakura, who is a part of the Leaf Village. This could lead to internal conflicts within the Akatsuki, and perhaps some of their plans against the Leaf would be thwarted earlier. Also, Sakura might be targeted by the Akatsuki more because of her connection to Itachi, adding more danger and drama to the overall story.
