In the following excerpt
Prominent absentees from the event apart from Punia, were cricketer Ravindra Jadeja, Asian Games gold-medallist shot-putter Tejinder Pal Singh Toor, and silver-winner quartermiler Mohammed Anas, all of who were picked for the Arjuna award this year.
I think instead of who, whom should be used. Because I have never seen who in these sentences.

It should be “whom”.
✔️Yes: All of whom were picked for the Arjuna award this year.
It’s whom because of the word “of”. (It’s acting like an object, not a subject. The technical terms are “objective and subjective case.”) (See here (1) and (2))
You would say “all of him,” not “all of he”, so whom is correct.
In spoken English, you won’t hear whom too often, but it remains “correct”.
Whom remains important in business writing, technical writing and formal contexts.
Many English speakers do not know the difference between who and whom. In some places, it hardly matters, because using who when you should use whom is so common that it’s not even considered much of a mistake. — Lawless English
There is plenty of discussion here on ELL as well.
You are correct, it should be "whom".
By the traditional rules, "who" is used for subjects and "whom" for objects. "Who asked the question?" "Who" is the subject, the person doing the action, so that is correct. "You asked whom?" "Whom" is the object, the person receiving the action, so that is correct.
The word "of" is a preposition, and so what follows is the object of the preposition.
The example you give may be a little confusing because "who" sort of sounds like it's the subject. If you said, "These are the people who were picked for the Arjuna award", "who" would be correct, because "who" is the subject. But when you say "all of whom were picked", the subject is "all", not "who" or "whom". "Whom" is the object of the preposition "of".
Note that in modern English we have few cases where we use different forms of a word for subject versus object, mostly just pronouns: who versus whom, he versus him, etc. This is unlike some other languages where there are routinely different endings for almost every noun. So many English speakers are getting sloppy about who versus whom. You'll often hear people say things like, "You gave it to who?" when technically it should be "to whom". If you go by the principle that whatever the majority of people say and write is by definition correct, then "whom" is obsolete or near obsolete.
Directly after a preposition is the place which most tenaciously hangs on to whom - perhaps because this is a context where there is no doubt that whom is the (traditionally) correct choice.
Not everybody uses whom even here, but I think anybody who uses it at all will use it after a preposition such as of.
