There is no such thing as “para” liturgy. It is either liturgical or it is not, in which case it would be considered devotional.
The Liturgy of the Hours IS Liturgy. The rule is simple: if the prayer is regulated by an official liturgical book, then it is a form of liturgy (Mass, benediction, the liturgy of the hours, blessing of sacramentals, etc.).
If it is not regulated by official liturgical books, then it is devotional, e.g., rosary, divine chaplet, adoration, etc.
Practicing Catholics should be both liturgical and devotional. Both practices complement each other.
