Imagination is inherently based on knowledge, and it's particularly true for Lawrence. His imagination operates as the simulated reengineering of the empirical data he previously memorized (see the "Possibility Matrix" section), so it cannot be used to create anything truly new since any imagined being/item is entirely based on 100% accurate information.

On the other hand, he can instantly, perfectly and retroactively memorize any phenomena on every level in its most infinitesimal details. Combine that to his truly limitless processing capabilities, and he can effectively retro-reengineer virtually anything into anything else, instantly breaking down a dust grain into a primordial soup of sub-quantum proto-particles, and masterfully re-evolving them into a thousand universes worth of brand new possibilities.

So while Lawrence cannot create new information from nothing, his reengineering expertise is so incredibly advanced he can forge nigh-infinite possibilities from any material available.
