I thought the developers ending was for beating it with Crono and Marle only at the very beginning in ng+?

That's the common way of getting it, the way you're supposed to see it the first time. However, you will get the same ending if you beat Lavos in the Ocean Palace so that he never actually kills Crono, whether you're in new game+ or not. But to do that on the first run-through is the real trick in this game.

*Shameless Advertisment here*
I've updated my LLG FAQ to include a strategy for a LL party to beat him a NG+ (It's 100% impossible without the equipments from later)

That much said though I can point out a few things that will help most parties overcome him.

Lavos has 16 (**) speed and does the following attack pattern:
Destruction Rains (Physical)
Chaotic Zone (Magical)
Needles (Physical)
Repeat

How much damage these attacks do depend upon your stats, but Destruction Rains will most certainly be the heaviest hitter here, and Needles will do most damage against a single character. You'll want to boost your Physical Def as much as possible.

You have:
The Safe Helm
Vigil Hats
Gold Erng
Silver Erng
Aeon Suits
Green Dream
Shields

Available on a first playthrough, which you should be able to shuffle around to survive all his attacks provided your party is in the 30-40's. There are Six Speed Speed tabs IIRC available before then. Your best bet I think is using Crono Ayla and Frog, who have the highest natural Speeds, and using Speed Tabs to get them roughly equal. You can charm unlimited Lapis and Barriers in here and also but Full Tonics I think, you should have plenty of Elixirs too, rely on those to heal. Your best place to revive is probably after the Chaotic Zone, you'll need status protection, hence the vigil hats.

Also, if you are really struggling for turns you can give Crono the Slasher (+2 speed) and designate him a healer only, you can even give him a rage band.

Best of Luck! Hope I helped

All those items I stated are available before facing Lavos in Ocean Palace.

And what is Life 3?

Surely you'd need Robo instead of Frog for that though?

If your Marle can survive all the attacks (except maybe his needles) and is fast enough then I don't see why not, however be aware that Marle only has 8 speed though and will be 2-Turned everytime by Lavos if she doesn't have Haste or isn't pumped with Speed Tabs
