Just put I after K and the subgraph.

​That works. It is even better when I put both H and I after it.

I also found a way to get resources at the correct place.

​I changed to a digraph:
    #+BEGIN_SRC dot :file test.png :cmdline -Kdot -Tpng
    digraph {
      A
      B
      C
      utilities [label = "Utility's"]
   
      D
      E
      F [shape = rectangle]
   
   
      subgraph cluster_resources {
        color=blue
        resources [label = "Resources"]
      }
   
      G
      G_ [style="invisible"]
   
      K
      subgraph cluster_ta {
        color=blue
        {rank = same; L, M}
        L
        M
      }
      H
      I
   
      {rank = same; D,  E, F}
      {rank = same; G_, K}
   
   
      A -> F
      B -> F
      C -> F
      A -> D
      utilities -> resources [style="invisible"]
   
      E -> F
   
      F -> K [dir = back]
      F -> G [dir = back]
      F -> H [dir = back]
      F -> I [dir = back]
   
      G -> G_ [style="invisible"]
   
      K -> L
      K -> M
      L -> M
    }
    #+END_SRC

There is only one problem: I see the arrowhead with:
    utilities -> resources
and:
    'G -> G_'

Is there a way to get rid of those?

​I found that also:
    [style="invisible", arrowhead = "none"]
