Is it permissible to repair a phone using the "Odin" program after learning that the meaning of its name is "god of the Norse: wisdom," which is a polytheistic meaning?

There is no need to research and delve into the meanings of program names; that is a blameworthy over-elaboration, and the default ruling for things is permissibility. Even if it becomes clear that a name has a forbidden meaning, that does not mean it is impermissible to use the program.
