My children ate what they were given, or did without. There'll be another meal in a few hours.
I have 100% survival to adulthood. Let them phone childline.
Care has to be exercised tho, it's very easy to give kids life long trauma related to food(s) by the way that food is used as form of abuse. The "This is what's for dinner, like it or lump it", without the follow up consideration of "Well they didn't eat this one, I wonder why that was?"
There are foods that simply putting a mouthful of it in my mouth will cause me to puke, in part related to the way people in a position of power used food in ways that shouldn't.

I have an intense dislike of certain foods, particularly those that are extremely bitter. As a child I also had poor tolerance for things that were painful (eg. chilli, fizzy drinks, toothpaste), and a strong aversion to certain textures (fatty meat, slimy fruit and veg), though as an adult I've learned to HTFU about those when necessary.
My parents approached this with the textbook boomer tactics of starving (didn't work, I was more than happy to not eat
[1]), force-feeding (pretty much the above puke reaction), and bait-and-switch (usually thwarted by me having a functional sense of taste
[2]). I survived and eventually they saw sense on a day-to-day level. It's not like I was doing it deliberately, and there were plenty of foods that were boring or I simply didn't like but would pragmatically eat for the sake of an easy life.
Which didn't change the fact that my dad took my refusal to eat certain foods as a deliberate offence; I ruined countless family holidays and special occasions by not eating something or other, causing him to go into a sulk for weeks. My mum (who I later realised was fucked up about not being able to have children) internalised all this as a failure to mother. I'd occasionally get into trouble with other adults for not eating things, but mostly I avoided situations where I might be expected to eat unsafe food. Frequently I'd fuck up and think something was safe based on verbal description or visual appearance and then discover it wasn't. (This is far more offensive than not wanting the thing in the first place.)
(FWIW, it never occurred to me to phone Childline or similar. All this was normal and ordinary, plus I had the sense to know which side random adults would be on.)
I waited it out, accidentally upping the ante by coming out as queer, not being as academically gifted as everyone hoped, and general disinterest in substance abuse. Once I left home I could eat what I liked, mostly without being judged, and finally achieved a healthy weight
[3]. I still believe that I'm a fundamentally bad person for not eating things, of course. Including things that adults are allowed not to like and the stuff that I can no longer tolerate for digestion/allergy reasons. I continue to avoid situations where I might be expected to eat unsafe food, and generally lose interest in eating when stressed.
YMMV, and I don't claim to be any kind of expert, but I'd suggest this sort of thing isn't a hill worth dying on. Don't force or coerce someone to eat things they don't want to, but that doesn't mean you have to go to extraordinary lengths to prepare extra meals for them either. Make a basic effort not to contaminate things they'd otherwise eat, and if they don't like what you're cooking let them feed themselves without making a drama about it.
[1] I don't really feel hunger, I just get into the habit of eating.
[2] I got into trouble on a couple of occasions for refusing to eat food that had clearly gone off, but that their smoker tastebuds couldn't detect a problem with.
[3] It's got marginal again, because reasons. I'm keeping an eye on it.
