Many Codefendants For Dormant Hoa Civil Declaratory Judgement- Pool For A Lawyer Or Should We Have Separate Lawyers?

My subdivision currently has a mess on its hands. What originally was to be a 250 household subdivision with an HOA but the builder went under during the housing crash 15 years ago. Only 42 homes got built and the HOA never got handed over to the owners before it went through bankruptcy. There is currently a builder that owns the over 150 vacant lots and the common areas but they've discovered this dormant HOA (non payment dissolved in the eyes of Illinois but never officially killed) that never got handed over (most didn't even know it was there as there are very few original owners left). The new builder via the CC&Rs has no voting rights since it has only vacant lots and no certificate of occupancies but is seeking a declaratory judgement to change that and named the 42+ houses as co defendants.

Should we pool together to get a lawyer or should we all get our own lawyers? The subdivision is mostly aligned at wanting to kill the HOA for ourselves as long as the builder retains ownership of the common areas (drainage basins) and create a new HOA that we wouldn't be in (slight differences of opinion but mostly of that view). That being said as you would imagine with 42 defendants there are various levels of urgency or seriousness of this threat so not all want to pay for a lawyer just yet.

My question is more basic than that though, should we be pooling together at all, form several subgroups that are almost 100% aligned, or each get our own representation?
