I don't get this divide.In TSR era D&D, utility spells were important, and often more important than combat spells. Most old school players knows how only a newbie Magic User takes Magic Missile at first level, the real powerful spell to take was either sleep or charm person. Spells like levitate, knock, teleport, invisibility, and dispel magic were very important. Sure, you also had combat spells, but crowd control was more important than DPR: hold person, sleep, stinking cloud, etc. If I were to make a guess, I'd say over 50% of your memorized spells were utility spells.
Combat is more than just DPR attacks.
Knock seems the only pure utility spell there.
Teleport is very utility heavy, but also a great combat retreat spell or part of scry buff teleport attack plans.
Levitate can be either utility or defensive in combat to stay out of melee.
Invisibility is utility for scouting and such but also useful for getting around in combat or getting a combat advantage.
Dispel magic is useful for countering opponents spells or breaking their ongoing magical effects.
Charm person can turn an enemy into a friend.
Sleep is a combat spell, I have never seen a situation that calls for a utility insomnia cure (though someone could work hard to contrive one in an adventure).
While half may have had some out of combat utility, I would guess a much larger percentage had combat utility.
Affect normal fire made your torches last longer, but not much combat utility that I could think of. Identify was an out of combat only spell, though learning command words for looted wands and their charges (approximately) was definitely useful for combat.
