By the time the aircraft took out the light It would have been well off the centre line could this be more to do with the fact that 2 tyres were deflated on the left gear.
I'm sure they will be checking the QAR data (if they kept it) from the last few flight to see if there were any effects on the 3 previous flights, where the part was missing, of additional rudder use on take off that could point to this problem with the gear skewing.
Time will tell but it will not look good for AF if thier servicing is a contributary cause to the accident.
