Hey Souja? He probably didn't even know about it. I never saw it when it was made, so it didn't get added to the directory (I add what I can but I'm not perfect). So it's not really a reason to get upset..
Odin endowes his Odin Force to The Belt of Power, Thor uses this power belt/armor to double his strength plus, and eventually defeats an uber powered Thanos that would threaten the universe. ( Thor v2 #527)
A weakened Odin defeats The Dark God Zelia, this particular Dark God was supposed to be as strong as Odin/Pantheon God. She also had Odin' Power. Well, Odin reclaims the power she stole from him, and scatters The Dark Gods among the solar winds. A WEAKENED Odin!
LT only takes notice of events when they have the potential to pose a threat to the Multiverse.
And though Odin's death was felt across all planes of reality, it was hardly an event that LT would care about.
"A great tactician creates plans.
A good tactician recognizes the soundness of a plan presented to him.
A fair tactician must see the plan succeed before offering approval.
Those with no tactical ability at all may never understand or accept the plan.
And when a mind is too deficient in understanding, the resulting gap is often filled with resentment."
