Starting with PHP 8.1,
mysqlihas a new default error reporting mode that throws exceptions.As WordPress handles error conditions on its own, this is not needed.
The default error mode is already adapted with WP Core 5.9+, but on older versions the above changes means that you cannot even update WordPress sites on PHP 8.1, as they fatal with an uncaught exception.
Therefore, WP-CLI also sets the default error reporting mode now to avoid these fatals.
