I have served hosted Muslims, Buddhist vegetarians, ethical vegetarians and recovering alcoholics literally hundreds of times over the last 25 years. My family and friends are Pakistani, Indian and Chinese for the most part, and most of the Chinese are Buddhist vegetarians, because that’s the sect my wife belongs to.
Unless they are close friends, Muslims will generally inquire about both halal meat, alcohol and also any additives that might contain pork products. If they care. If they are close friends they already know I will not try to feed them something with any of those. Many others will tell me not be too concerned about a tiny contamination. I did have one Muslim classmate who wouldn’t eat cake because there was alcohol in the vanilla essence. He also tried to convince other Muslims at the party that they shouldn’t either. He’s not getting invited back.
The recovering alcoholic has never raised wine in food as an issue. I’ve certainly served him Beef Bourgogne and Veal Marsala. I wouldn’t serve him a very boozy fruitcake or spice cake.
The Buddhist vegetarians unless they are monks or nuns basically say they don’t want to trouble the host and will eat whatever they are comfortable doesn’t have visible meat in it. So if I used a bit of gelatin or fish sauce it’s okay.
We have a couple who are Brahmins, who have a boatload of restrictions. They can’t eat anything at our house, they can’t even drink water in glasses we use. They come to our house socialize but don’t eat or drink. Oddly enough they will eat at restaurants. Apparently food prepared by non-Indian people is fine. They just suspect I’m from a lower caste, I assume. Their kid is my kid’s bestie or I’d tell them to GTFO. I’m pretty sure the kid’s gonna tell them that as soon as they pay for her college 
Kids have eaten all kinds of food in our house that has alcohol in it. If anyone pulled that stunt from the OP on us, they’d be cut right out of our social circle. Unless your kid is Muslim/Jewish/Jain/etc and I know he’s Muslim/etc, they eat what I cook. If you have any restrictions that aren’t obvious, you’d better tell me in advance.
At the last sleepover I served Crepes Suzette. With almond flour crepes, because one of the girls has a gluten allergy/intolerance.
Ethical vegetarians or vegans who get preachy are never invited back. I can make perfectly nice vegan food for you, but if you tell me to lay off the butter on my own bread in my own house, you’re an asshole. Unfortunately this has happened.
