وَإِنِ اضْطُرَّ الْمُحْرِمُ إِلَى أَكْلِ لَحْمِ الصَّيْدِ فَقَتَلَهُ فَعَلَيْهِ الْجَزَاءُ.
Translation: If a person in ihram is compelled by necessity to eat game and kills it, compensation is still due.
Idturr(a) describes compulsion by necessity. The passage expressly retains game compensation where game is killed for needed food.
Do not confuse this with killing an attacking predator in self-defence: the facts and liability rules are distinct.
