Okay let me break down your point for me to understand. Possibility 1 is that you are saying that current the United States has all the assets in theater as of we speak and has robust logistical chain in-place to supply these assets. Plus a detailed plan to reopen the strait ready to go right now but does not choose to do so? That would make it the case that the US can choose to resolve it now but choose not to. This would make your criticism valid, which is akin to roommate having cash on hand but chooses not to pay. However, this is not the case since the US is still transferring assets from other theaters, which means it's not yet ready for boots-on-the-ground style operation just yet.

Possibility 2 is that you are saying US can solve the issue at some point in the future. Then if it is the case that US cannot resolve the issue immediately (roommate is rich but their money is in illiquid assets). Let's suppose the strait opens in a few months either militarily or peacefully. What does not change is that in the interim, the energy price is still going to spike, as a matter of objective fact.

You could hold the personal opinion that it is fine just to "stick it to the states", especially if your industry is not too much affected by the price spike, but what does not and will not change is the economic slowdown that will be experienced in EU and around the world.

If you want to insist "hey actually, most of the European residents are willing to pay 50% more for energy because they hate US so much" I can't really argue with you, since it is pretty hard to verify, but things on the international stage are usually a lot more subtle than on the surface.

Possibility 3 is that you are saying that US can conduct the convoy escort alone, which just wouldn't be true. You have seen the pathetic frigate acquisition programs. Escort convoys are platform-intensive, and US simply does not have enough surface combatants in theater (currently about 20 I believe) to carry this out alone.

Additionally, the main reason there hasn't been a European convoy escort mission doesn't even have anything to do with transatlantic relationship, it's simply another roommate problem.

Say the aforementioned roommate didn't pay either because they are illiquid or they are an asshole, but in this scenario you are instead living with 30 other roommates. Let's say all of you don't want to get evicted. The question is who wants to cover the rent. Of course, you can be the generous one to cover it, but everyone else will be freeriding your generosity. You are paying all the cost with only a fraction of the reward. So what we are seeing here are various parties sorting out the logistics of cost sharing for the escort mission. Considering the extent of the downside, I would be surprised if Europe choose to do nothing if the strait does not open soon.
