They try. I've seen it many times at LAS with groups of older Japanese tourists, who commonly don't speak English.

SFO is contract security, but they were screaming at Germans, Koreans, and Japanese to play the name game. The Germans ahead of me caved, but I very politely over and over asked in German why they wanted my name when it was very clearly written on my boarding pass, and helpfully showed them a few times where my name was written. In the end after several minutes of shouting, I was sent on in disgust. The Germans around me congratulated me, and the TDC moved on to scream at some bewildered Koreans.

I've had conversations many times with other travellers in German, or in French, at the TSA checkpoint. But the TSOs expect us to speak and understand English when we reach them. I think that there is the stereotype of young to middle-aged Europeans all being able to speak and understand American English, which just isn't the case. Your countrymen tend to speak the best English in my experience, but not every young person speaks English, and certainly the further eastwards one goes the less that happens. And knowing school English learned in Europe isn't the same as understanding TSO barking in regional American accents!

I try and just realise that they are being very ignorant, and don't let it annoy me if possible.

In Germany by the way I believe that it is required to speak at least 3 languages to be airport security. I think that it must be the same in the Netherlands and most places around Europe. In Canada I can use English or French with no issue as CATSA must offer up both options. But I don't think that TSA has any such language requirement or even any sort of stated option to request anything else.
