Question about a land trust trustee: what are your thoughts about using a title and trust company as the land trust trustee for anonymity purposes?

You get the benefits of anonymity with the Land Trust and you can further solidify your asset protection strategy by having the beneficial ownership interest in the Trust owned by let's say a Nevada or Wyoming Holding LLC. 

An LLC is useful for two things: anonymity and legal protection.

Is it unheard of to use a property management company to provide anonymity?

Additionally, put the anonymity pieces into the structure through the use of trusts (similar functionality of the Wyoming LLC anonymity.)

You will want to set up an LLC taxed as an S-corp (you can do an anonymous WY LLC), although some say use C-corp but no idea why really,  and another an anonymous LLC taxed as a disregarded entity.

I am aware that setting up a Land Trust can create anonymity.

First by owning one LLC with another you can create anonymity in ownership to a limited degree. 

Use trusts if you want anonymity.

But you can either create a multi member LLC instead or have your single member LLC owned by a holding LLC in a better state like WY that will also give you anonymity.
