That has been a key problem of NATO’s defense posture for many decades: How believable is it that the US will risk complete self destruction to protect the freedom of European countries? And iirc that was one reason during the cold war to switch from “massive retaliation” to “flexible response” as a deterrence doctrine.
As it was then, even now, I think, it is not about assuring the adversary that the US will be involved—there can’t be certainty about that. It is more about changing the probabilities for a US involvement. That is the main reason behind the troop movements to NATO’s eastern border, e.g. US F-35 fighter jets and an infantry batallion. An operation killing American soldiers in combat is massively more risky (and therefore, hopefully, much less likely) than an operation without this risk.
Telling the US “Get out of the Baltic states (even though you have guaranteed their safety), or else” is quite different from “Don’t get into Ukraine, or else”. Furthermore, there are troops in the Baltic states of other NATO countries with nuclear weapons, France and the UK.
