The LRASM is based on the JASSM, has a range of approximately 300km. The Kongsberg JSM is based on their NSM, has a range of approximately 290km. The main differences appears to be sensors and avionics, and warheads. The LRASM has an advanced active/passive radar seeker, with two-way datalink, and autonomous AI navigation. The LRASM has a much larger warhead, approx. 1000kg.
The JSM utilizes an advanced IIR seeker, with autonomous target recognition. The JSM follows a very complex course for stealthy ingress to target. The JSM has a warhead of approx. 125kg.
Really, we'd be lucky to get both weapons, The LRASM is the more capable ship/sub launched weapon. JSM is a better weapon for fighter aircraft, as it's sized to fit in the F-35 internal bay.
