I don't see how New-Item would work, it would just create a new file.
I also don't see how the Copy-Item command would work (and in testing it doesn't).
Since the touch command just updates the Last Modified timestamp on a file, here's an equivalent.
(Get-Item somefile.txt).LastWriteTime = Get-Date

Open in new window

if you go on a linux machine and touch foo
it will create a file called foo; same as New-Item

You're right, I forgot about that functionality of touch.  So I suppose that the answer depends on what functionality of the utility needs to duplicated.  Otherwise, a function could be created to handle multiple functions depending on conditions.
