Seems bad to me in that it sounds like the US using EU/Nato funds to purchase their own equipment.
Ukraine now arguably has the most capable army in Europe, by some measure. Certainly the one best adapted to the seismic change in battlefield tactics of recent years. The US, UK and just about everyone else has a lot of catching up to do. European countries seem to get this. US hubris, especially under the current regime seems to mean they don't.
I can't remember where I read it, sorry, but apparently the UK is to stop training Ukrainian soldiers, because a lot of what the British, and various others based here, trainers were teaching them has become out of date as the conflict has changed. To the extent that Ukrainians are teaching the Brits and others their tactics. I don't think that included the US, as you say, they don't think they've anything to learn, the rest of us aren't so arrogant and will listen to anyone who has relevant experience and has developed tactics which work.
