Honestly, I do not know what you are basing that on.

I think you are mixing up two things: EU members trying to avoid immediate escalation with the US, and Europe preparing to reduce its dependence on the US over time.

Also, because Spain is in the EU, formal trade retaliation against Spain is not just a Spain-only issue. External trade policy is handled at EU level.

It’s a bit pointless though, isn’t it? Seeing as Spain is part of the EU.
