Yes, the top-level domain is still just a domain. I’m not aware of any public Internet services which are reachable from a TLD directly, and it’s strongly discouraged by ICANN, but there isn’t any technical limitation preventing e.g. someone at Verisign from setting up example@com.
I didn’t understand this one. How do you have a no dot domain? Like you need to distinguish from example.com or example.wtf
Edit: do you mean if you own
.googleyou can have youremail@googleaddress?In response to your edit.
Yes, or countries could use their cctld, e.g. email@us or noreply@uk.
Or any tld owner could do the same with theirs, of course.
Pretty cool

example@com.you could also send mails within your local network, the hostname just has to resolve and have a mail service running
