How can I use different bullet list markers for items in a single a list?

A function cannot use “set” and have it take effect outside itself, but we can get close to the required contract like this.

#let CoolFunction(it) = {
  // This function will fail with list items other than 1 and 2..
  let symbols = ("1": $subset.eq$, "2": $supset.eq$)
  set enum(numbering: x => symbols.at(str(x)) + ":")
  it
}

#show: CoolFunction
+ Proof of 1
+ Proof of 2

// alternative calling mode which only affects one numbered list
#CoolFunction[
+ Proof of 1
+ Proof of 2
]

Note that the function must get access to the list itself to be able to change it. With a show rule, or passed as an explicit parameter.

If you want to do this with list instead of enum I think it’s possible but more complicated, you’ll have to reimplement a little bit of list layout and item placement to change the marker per item, which just seems unnecessary.
