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.
"The Grand Admiral was smart and subtle, but never used his brilliance to show up or humiliate anyone.
He demanded results, but never perfection, and had amazing stores of patience for those who were truly working to their fullest ability.
It was a pity Thrawn's style of leadership hadn't spread through the rest of the navy.
If that happened, he suspected, the Empire would stand forever."
