Hi,
I tried to find some Microsoft Learn on this question, but without luck.
Based on my research, LAPS group policy is based on computer configuration, you can deploy the policies on the OUs which containing PCs you want to manage through the LAPS, no need to deploy all the LAPS related GPO on the domain level.
Operation details can be found in the operations guide
