Replace Power Steering Link due to a oil leak? on 2005 Lexus RX330

The dealer says since the leakage is from interior - tie rods. Due to complexity, they can't disassemble and fix the leakage. So i need to replace the whole Power Steering Link.

1. Is the car safe to drive?
2. Is it possible to fix without replacing the whole Power Steering Link?
3. Any advice welcome
