Thats standard for military aid to other countries. Almost all US military aid to Ukraine was spent in the US for equipment purchases. The benefit for Ukraine is getting the weapons to use in the war, although it's worth noting a decent portion of the military aid will be spent by ukraine on domestic manufacturers.
Also €30 billion is financial and humanitarian aid, almost all of which will be spent in ukraine proper.
> Also - I think that EU is going to try to figure out a way to get that Russian money.
It's already sending the interest on the money to Ukraine, that alone is worth billions a year.
Simply seizing the rest is more complicated and additionally probably not preferable. Keeping the rest immobilised gives europe and Ukraine a substantial bargaining chip in negotiations with Russia when the war eventually ends. Either Russia agrees to concessions to get the money back or it doesn't and it agrees the money can be sent to rebuild Ukraine.
