The insurance company will probably compensate her for her loss.
Literal
Insurance-company [topic-は] her loss [obj-を] compensate probably.
補償する is the verb for 'compensate' (as opposed to 保証する 'guarantee' and 保障する 'secure' — the 保 triplet is a classic learner-trap). Insurance contexts use 補償 for payouts to injured parties. ~だろう closes the prediction in plain form.
