Not that I have read it except in very small extracts but possibly the 1922 'Oxford Text' of the Seven Pillars of Wisdom would provide some enlightenment since it runs to 335,000 words rather than the 'first' abridgement (1926 edition) which got cut to 250,000 words while the second abridgement of 1927 Revolt in the Desert only runs to 130,000 words.
It is very dangerous to base any assessment of an individuals views on what is presented in popularistic film adaptations of books let alone the books themselves. Often changes are made wholesale in them - especially when the original author is dead.
There is a separate issue that authors state views and opinions which may have little reality to how they thought or felt at the time of events. Although Lawrence kept notes of events and used them as the basis of his work he burnt them after writing the original draft of the Seven Pillars but then lost the original draft so had to re-write it from memory.
There is a site which is dedicated to T E Lawrence which seems to contain academic discussion and lots of information on the man that you may find of interest here.
