Setting the required attribute in the context of a lightning-record-edit-form only brings you the little red required indicator next to the combobox label, but the validation itself you have to implement yourself, because the native validation can't be used here. So you must handle the validation for the custom picklist field in your LWC JS controller. This issue even exists with standard components like the lightning-combobox, see for example: https://salesforce.stackexchange.com/questions/291663/required-attribute-on-lightningcombobox-ignored
