With 意思 being いし{HL} (頭高型) and 疎通 pronounced そつう{LHH}, I think I've only heard
意思疎通 pronounced いしそつう{HLLHH}, but since middle-low is not a pitch accent
pattern, I'm starting to doubt my ears (which quite frankly fail me more often
than they serve).

Also complicating the issue is 意思表示, despite its morphological resemblance to
意思疎通, seems to be いしひょうじ{LHHHLL}.

So it seems the only possible explanation is 意思表示 is taken as a whole word,
but 意思疎通 isn't? 意思疎通 does appear quite commonly though. Or am I hearing it
wrong?

意思疎通 pitch accent
I hear both いしそつう【HLLHH】 and いしそつう【LHHHL】 commonly. I believe 意思疎通 _is_ a
lexicalized compound, but middle-low is not an uncommon pattern at least in
四字熟語:

  * 意志薄弱 いしはくじゃく【HLLHHHH】
  * 支離滅裂 しりめつれつ【HLLHHH】
  * 春夏秋冬 しゅんかしゅうとう【HHLLLLHHH】
  * 因果応報 いんがおうほう【HLLLHHH】
  * 森羅万象 しんらばんしょう【HLLLHHHH】

Some are even more complicated:

  * 切磋琢磨 せっさたくま【HLLHLL】
  * 一蓮托生 いちれんたくしょう【LHHHLHHHH】

On the other hand, 意思表示 is always いしひょうじ【LHHHHL】. I don't know why.
