Last I checked (years ago) titanosaurs were thought to be very round, even 
somewhat dorsoventrally compressed, so this doesn't sound like they could 
roll over on a side in the first place... how much sprawling did their 
forelimbs allow?

If it completely trips, the head falls from a tremendous height, so I guess 
it dies... but then I don't think it's likely to trip in the first place. 
Being so huge, it has plenty of time to react. The apparently unossified 
carpals of titanosaurs could have been an adaptation to cushion 
harder-than-usual impacts.
