A new Tramp buffer is created in function `tramp-get-buffer'. But this
is called many times; creation a new buffer is not its major
functionality.

You could apply the appended patch, which separates creating the buffer
into a new function `tramp-create-buffer'. This could be used for
`debug-on-entry' then.
