We viewed your photos. This does not look like a disease or insect issue. The hollies are trying to establish themselves and have been subject to pretty rough growing and site conditions (winter damage, construction, compaction, etc. ) Hollies can tolerate partial shade but will be slower growing.

Not clear if you are using a company for the lawn only or shrubs also. Do not spray unless the pest or disease has been identified and you know what you are spraying for.

The new growth looks pretty good. At this point, all you can do is make sure the shrubs are watered during dry periods. Mulch should be no thicker than several inches and keep away from the base of the trunks. Look around the base of the shrubs and make sure they are not planted too deeply.
