Yes, I think the EU is going to be dependent on US tech (other than EUV lithography machines, very cool) for very long time. Even those data centres, while run by Europeans, are still being made with almost entirely US tech. But at least the EU companies can borrow some oil money and buy in the stuff developed by someone else's R&D spend, which is a nice shortcut to have available.

Well, ASML's EUV light sources are based on licensed US IP from Sandia Labs, and manufactured in the US by CYMER, which ASML bought, but they still operate and manufacture out of California, so the EU is not sovereign/independent here (neither is any country).
This doesn't mean much anyway, since despite ASML being European, their machines all go to export and EU doesn't put any of those machine to good use domestically, with the most cutting edge semiconductor fabs on EU soil being the Germany based TSMC fabs on the much older 16 and 12nm nodes, far bigger than the 3nm that Taiwan and US operate domestically.
