If all subnets are a part of same vlan, then the network segregation using subnets does not make sense

So, does Vlan and Subnetting go hand in hand? What I meant is, if we need to use subnetting, the do we need to also make sure each subnet is part of a different vlan? In 98% of the cases, YES. You ...

Unsure about our current setup + routing issues (Diagram attached)

I fully second the above answer - this network could use a redesign and proper hierarchy. Considering small scale of this network you would probably be okay with: a set of core switches, don't rely ...

Unsure about our current setup + routing issues (Diagram attached)

From the diagram, your network has grown convoluted. You should redesign with a clear structure (collapsed core, hierarchical two-tier): designate one of the switches as core connect all central ...
