The hardware is produced in Asia but American controlled. its still a dependency on being supplied by American companies.
"Only services" covers a lot of critically important things. Clouds services and payment systems, for example. Even just one American company like AWS could turn off a huge chunk of European economies.
That is just tech. What about fuel? machinery. https://www.consilium.europa.eu/en/infographics/eu-us-trade/
After decades of globalization, everyone is just extremely dependent on everyone.
I think hardware is a bit complicated by the way. A lot of hardware is also not US controlled. For instance ARM Holdings is British, Japanese, or global depending on how you look at it and quite a lot of vendors rely on ARM's reference designs. Europe also has a lot of important chip designers, but they are more focused on embedded systems and support chips, like NXP and ST Microelectronics.

Why European governments and increasingly companies are trying to move away to European alternatives. It all starts small, but e.g. a bunch of governments are already disentangling from Office. The sale of the maintainer of the Dutch DigiD infrastructure to a US company has been blocked (would have happened without any blockers a few years ago). Countries are reducing US arms purchases in favor of European alternatives.
It's like turning a mammoth tanker, but it is slowly happening.
Let's just hope we have critical mass before the right-wing populists take over, big tech has been intensively lobbying them in recent years [1]. So much 'for the people', like they always proclaim.

Yes, but services are easier to replace than hardware. And control is something you have, and then you don't have if the country in which you operate decides otherwise (or US presidents throws another tantrum).
Companies use AWS because it is there and others used it, so they got ball rolling. It doesn't mean one couldn't replace it with another service, most probably more pricey one. If there would be some kind of war, then one doesn't need to have servers in US, and European ones are right there.
You can't easily replace e.g. lithium or other metals.
Fuel is problematic, but there are places that are closer that could sell them (middle east, if we ignore current Russian state of mind).
As for machinery, it is hard to guess what kind. Germany produces a lot of it, and I would guess China also.
Not sure about pharmaceuticals.
Generally US is not our greatest import partner, China is. And we have a big internal market also.
