I've pulled together the script below from various different sources that drop the dependencies updates the collation then recreate the dependant objects. This solves the problem of updating the collation of columns that have dependencies (indexes, foreign key constraints, etc.)
/*******************************************************************************

* Created 2017-06-16 By Philip C
* Shared on: https://mcmap.net/q/246728/-how-to-change-the-collate-to-all-the-columns-of-the-database/44587493#44587493
*
* This script will check individual columns collations and check it against the
* database default collation, where they are different it will create the scripts
* required to drop all the objects dependant on the column, change the collation
* to the database default and then recreate the dependant objects.
* Some of the code has been reused from stuff found online the majority from
* Jayakumaur R who created scripts to drop and recreate constraints
*
* Minor edit by Darren S to support SQL2019: Replaced AND ty.name !='sysname' with AND (ty.Name LIKE '%char%' OR ty.Name LIKE '%text%')
