Firstly, It is best to say "I know whose fault this is". Omit using "all" since this sentence already explicitly explains the fact that the person who is at fault is at fault for everything the speaker is referring to. Secondly, "do" is used correctly in your two examples. If you wish, "Do you do blood tests and physical therapy" can be changed to "Do you perform blood tests and physical therapy?" Next, "Does this company do airfare and accommodations" can be changed to "Does this company provide airfare and accommodations?" Finally, Missile-attack is hyphenated because it is linking the two together. It is an attack of missiles from North Korea.

1) "I know whose fault it *all* is" and "I'll know whose fault this all is" both sound fine. It sounds better to put the "all" immediately after the "it/this". 2) "Do" works fine in all these cases. 3) It is hyphenated because it is specifying the type of attack. Because "missile" is a noun and not an adjective, you join the two words with a hyphen instead of using a regular adjective-noun construction. English is a bit weird with hyphenating words though. There is a pretty thorough guide on how to use hyphens on this website though (http://www.grammarbook.com/punctuation/hyphens.asp).
