Well, Kumogakure is the only village that we known of that tried to control Kurama in the past. The result being Kinkaku and Ginkaku obtaining the Nine-Tails' chakra.

Also, the reason Konoha never attempted it before Naruto was because the First Hokage deemed Kurama too dangerous and so it was never a consideration to use it as a weapon. It's not that the concept wasn't appealing. Rightfully so, because even Minato decided to cut Kurama in half so Naruto could try to master a much more reasonable amount of chakra. Problem was Minato tried to seal more to give Naruto an easier time because there was a limit to what the Shinigami would seal. As result Minato had to seal more chakra than he meant to into Naruto, which would explain why Minato put a program into the seal at the Eight-Tail to trigger a portion of his chakra to activate to allow him to talk to Naruto and repair the seal. Just in case it proved too much chakra for Naruto, which it did. That's also part of the reason Jiraiya felt Minato intended for Naruto to weaponize Kurama's strength, but the mystery, especially for Gerotora, is why Minato felt Naruto needed that level of power in the first place. The answer obviously being Tobi later.

However, ironically, Naruto needed that extra power once he got control over it. Also by the war's end, the whole of Kurama was inside of Naruto again, making him even stronger than Minato intended.
