Whether the reverse reaction is possible is irrelevant. The important thing is that the forward reaction is possible. Your main scheme including azide reduction to amine is fine. Your synthesis of benzoyl chloride is no good because "methanoyl chloride" is unstable decomposing to HCl and CO.

AFAIK the idea of reverse synthesis is to break up the target compound (as shown) in ways which are reversible.i.e. go backwards to seek a reasonable way of going forwards.
If this were not the case then reverse synthesis becomes a random destruction of the target molecule and hence useless in practical (experimental) terms.
Yes, you can treat an amine to get a diazonium salt, as shown in the break down (reverse phase), but you cannot do the reverse reaction, hence it would be irrelevant in a reverse synthesis.
Example: If you are only interested in the reverse reaction then:

Maybe you have mis-interpreted my post in terms of forward and backwards. The OP uses a retrosynthetic step where they make an azide (it's not a diazonium) from an amine. This is not possible but in the forward sense, the direction in which the synthesis needs to go, azide to amine is possible (using hydrogenation is best, or use PPh3).
I think you have not appreciated that it is an azide not a diazonium.
