If it were me and my kid had lingering problems I'd have the doctors keep doing tests. I had to see like 9 doctors and do maybe over 40 tests but eventually I got some help from doctors for me. Even if they can't or don't want to treat long covid, if someone's suffering they can eventually either help treat it or refer to a doctor who can investigate more and try to help. If they call it asthma I'm guessing that's good because they gave you treatment for it? Which is better than them doing nothing.

I saw myself and some people I know get long covid and as part of it a lot of POTS symptoms. I have teenage nieces and one this past year started fainting, having horrible fatigue, extreme tachycardia, nausea, her electrolytes kept being low. Just like I'd gone through. Being a teenager the doctors blamed anxiety even though she couldn't stand. She did have anxiety already but in her life it'd never caused all those things. Eventually she started eating a lot of salty things and drinking a ton of Gatorade and felt somewhat better, but honestly I think she's still fatigued and trying to not tell anyone since everyone told her it was anxiety and didn't help her. I definitely worry a lot of kids are going through all this same stuff. But kids shouldn't have to fight to get help. I shouldn't have had to but at least as an adult I know doctors can have shortcomings and I'm the only one ultimately who will prioritize helping myself. Kids shouldn't and can't do all that self advocacy. And doctors blame them being bad at school instead of fatigued, anxiety instead of treating their tachycardia, etc. I'm worried a lot of kids will just think they weren't good enough to manage daily life everyone expected them to, when really they're sick dealing with health issues but those health issues didn't get noticed or treated.
