Inefficiencies in solar/fusion to mechanical energy conversion will be a binding constraint. Tether lift based systems will be worthwhile to push energy conversion steps out further to increase the size of the radiating shell doing the conversion as opposed to coilguns on the surface.
Even with those optimisations. Starting early is worth it since progress will bottleneck later. Diminishing returns on using extra equipment for disassembling Mars means it makes sense to start on earth pretty quickly after starting on Mars.
That’s if the AI doesn’t start with easier to access targets like Earth’s moon, which is a good start for building Earth dissasembly equipment.
It also might be worth putting a sunshade at Lagrange Point 1 to start pre-cooling Earth for later disassembly. That would kill us all pretty quickly just as a side effect.
Conventional tech is slowed such that starting early on multiple resource acquisition fronts is worthwhile
Exponential growth is not sustainable with a conventional tech-base when doing planetary disassembly due to heat dissipation limits.
If you want to build a Dyson sphere the mass needs to be lifted out of the gravity wells. The earth and other planets needs to not be there anymore.

Eating the biosphere is a very fast way to grow
Even assuming space is the best place to start, the biosphere is probably worth eating first for starting capital just because the doubling times can be very low. [https://www.lesswrong.com/posts/ibaCBwfnehYestpi5/green-goo-is-plausible]
There’s a few factors to consider:
does the AI have access to resources it can’t turn towards space
Biotech companies can’t build rockets but can build green goo precursors
how hard is it to turn green goo into rockets after eating the bipsohere
how hard is it to design green goo vs rockets and mars eating equipment
can the AI do both?
My intuition is eating the biosphere will be much easier than designing conventional equipment to eat the moon.
