iOS 10.3.4 is a pretty old version, so finding a compatible YouTube IPA might be difficult. Apple stopped signing this iOS version a while ago, so if someone is on 10.3.4, they can't download new apps from the App Store. But maybe there's an old version they can download. Wait, but how do you get an IPA that's compatible with such an old iOS?
: If you haven't "purchased" it before, sign into your Apple ID on a newer device, "buy" the free YouTube app there, then return to your iOS 10.3.4 device to see it in your purchase history.
If you cannot get an IPA to work, do not give up on iOS 10.3.4.
