Is there a way to access a collection's name other than through bpy.context so it can be renamed?

Collections are ID objects

In blender any ID object is stored in bpy.data Objects in bpy.data.objects meshes in bpy.data.meshes collections in bpy.data.collections etc etc

To rename a collection named "Bob" to "Frank"

import bpy

col = bpy.data.collections.get("Bob")
if col:
    col.name = "Frank"

Note if there is already a collection named "Frank" then numbers are appended "Frank.001"... as per unique naming convention.

Try this:)

import bpy

col_name = "Collection"
new_name = "My Collection"

# Find the collection by name
col = bpy.data.collections.get(col_name)

# Rename the collection
col.name = new_name

# Update the Outliner to reflect the change
bpy.context.view_layer.update()
